Neptune Aviation has finished their portion of the process of converting two of the U.S. Forest Service C-23B Sherpa aircraft to civilian SD3-60 certificates. The contract Neptune received last year could involve converting another 13 of the former U.S. Army Sherpas. The USFS expects to use them to haul smokejumpers, personnel, and cargo.
Neptune’s project began at the USFS facility in Ogden, Utah where the first two aircraft were done, but is in the final stages of being moved to the company’s facilities in Missoula, Montana for the remaining aircraft.
The analog instrumentation on the Sherpa aircraft the U.S. Forest Service obtained from the Army will be converted to glass flight decks using the Garmin G950 system. The work is being done by Field Aviation in Oklahoma City who started on the first one in October of last year.
The USFS received 15 of the aircraft which are known by a confusing list of names: Sherpa, C-23B+ (the military designator), and the civilian names of SD3-60, SD-360, and Short 360.
The contract, which has a potential value of $19 million, was awarded on July 29, 2015. At a minimum it will cover the flight deck installations in four of the SD3-60 aircraft with the possibility of converting 11 more.
The USFS expects to use the planes for delivering smokejumpers, cargo, and possibly firefighting personnel. They already have four SD3-30s, a variation, which is a little smaller with less powerful engines. According to Wikipedia the larger SD3-60 has a cruising speed of 249 mph, a range of 732 miles, and can carry 36 passengers (but fewer smokejumpers).
The schedule calls for the delivery of the first aircraft by the end of the third quarter of this year. Modifications on the remaining three Sherpas should be complete by the end of 2017.
On the Garmin G950 system, flight plan information is overlaid on a dynamic map displaying airspace, rivers, lakes, parks and woodland areas – typical landscapes for USFS missions.
The platform, which is 250 pounds lighter than the round dial analog system, also incorporates a terrain awareness and warning system, wide area augmentation system, and localiser performance with vertical guidance approach capability.
The last DC-3 operated by the U.S. Forest Service retired this week following a ceremony at the Missoula smokejumper base.
Known to the jumpers it hauled as Jump 15, it took off December 10 from Missoula and a flew to McClellan Airfield in Sacramento at 16,000 feet and 200 mph, unpressurized of course. There it will await an auction and a new owner.
The 71-year old aircraft, first operated by the Royal Air Force, was manufactured as World War II was winding down. The radial piston engines were replaced 24 years ago with turbines by Basler extending its life while providing more reliability and less maintenance. The aircraft’s sister, Jump-42, another DC-3, retired in November, 2012.
Approximately 607 DC-3s were built between 1936 and 1942. At that time their cost was $79,000. Most of them had 14-cylinder Pratt and Whitney radial engines.
With the two DC-3s now gone, the smokejumpers will be using some of the 15 C-23B Sherpa aircraft they received from the Army and two De Havilland DHC-6 Twin Otters. The Forest Service has been contracting for two additional Twin Otters but those will be phased out as the C-23Bs transition into the fleet after going through modifications, maintenance, and painting.
The specifications of the contract list a number of tasks that will be performed, including inspection, maintenance, preventive maintenance, rebuilding, and alteration of the Sherpas. Individual orders may include inspection, repair, painting, overhaul, rebuilding, testing, and servicing of airframes, engines, rotors, appliances, or component parts.
The work will be done primarily at Ogden, Utah, but may also be required at Missoula, Montana; Redmond, Oregon; Redding, California; and Tucson, Arizona.
Thanks and a tip of the hat go out to Chris and Jared.
After the Governor of Montana wrote a strongly worded letter to the Secretary of Agriculture complaining about what he called “nonsensical restrictions” that prohibit the use of the state’s five UH-1H helicopters on U.S. Forest Service protected lands, we started looking into the root of the problem. The former military helicopters are actually owned by the USFS, and are leased to the state under the provisions of the Federal Excess Personal Property (FEPP) program which require that the helicopters be maintained in full compliance with Federal Aviation Administration (FAA) regulations. But the Montana Department of Natural Resources and Conservation (DNRC) apparently does not hold FAA Airworthiness Certificates for the helicopters.
However, the USFS does not maintain all of their government owned aircraft in strict compliance with FAA regulations.
When we asked the USFS why the agency does not allow the non-certificated Montana aircraft to be used on USFS lands, Public Affairs Specialist Jennifer Jones, told us:
The Forest Service and the State of Montana Department have different standards and regulations to which each must adhere. Federal agencies, including the Forest Service, follow federal operational aviation safety standards that prescribe minimum specifications for the types of aircraft. These performance specifications provide an industry recognized margin of safety.
The USFS and the rules governing the loan of FEEP aircraft require the Montana helicopters to be maintained and modified according to FAA standards. Since these requirements are not met, the helicopters can’t be used on USFS fires.
Even though the USFS requires compliance with FAA procedures for their contracted air tankers and helicopters — and the state of Montana’s aircraft — the following USFS aircraft are not FAA certified, nor will they be:
Tanker 118, the HC-130H acquired from the Coast Guard that has been dropping retardant on fires this summer using a Modular Airborne FireFighting System (MAFFS). Neither the aircraft or the MAFFS have ever been certificated by the FAA.
The other six HC-130H aircraft that are being transferred from the Coast Guard to the USFS.
Four C-23A Sherpas used for smokejumping and hauling cargo.
Two AH-1 Cobra helicopters.
The eight MAFFS units used in military C-130s for fighting wildfires, and the modifications made to the C-130s so that they can use the MAFFS.
After the seven HC-130H aircraft are finished with their heavy maintenance and air tanker retrofitting, they will be owned by the USFS and maintained and operated by contractors. But they will not be brought under the FAA umbrella, according to Mrs. Jones:
The U.S. Forest Service’s firefighting mission is a Public Use mission in government owned aircraft. The Forest Service maintains airworthiness on Tanker 118 in accordance with Coast Guard maintenance standards, and the Coast Guard maintains engineering authority.
The Air National Guard and Air Force Reserve C-130s used to drop retardant with the MAFFS are maintained, modified, and operated according to military procedures.
Aircraft shall conform to an approved type design, be maintained and operated in accordance with Type Certificate (TC) requirements and applicable Supplemental Type Certificates (STCs). The aircraft shall be maintained in accordance with an FAA approved inspection program and must include an FAA approved Supplemental Structural Inspection Document (SSID), Structural Inspection Document (SID), or Instruction for Continued Airworthiness (ICA) for the airframe structure, as applicable with an ICA and Airworthiness Limitations Section (ALS) approved by the manufacturer (or equivalent) and the FAA for the airtanker role.
The USFS is not the only federal agency operating former military aircraft that bypasses the FAA. Others include the Coast Guard, NASA, and NOAA.
We asked a person in the commercial air tanker industry (who did not want their name disclosed) about the USFS not following FAA procedures:
The FAA governs the largest fleet of commercial aircraft in the world and are looked upon by foreign agencies as the golden standard. They can certify an A380 to pack 700 people but cannot certify a restricted category airtanker? The USFS is hiring a ton of ex-military people who all stick together with their other Air Force buddies and think the military is the be-all-end-all.
I think it would be fair to argue that the FAA knows much more about airtankers than the Air Force or the Coast Guard. The USCG maintenance program is not setup for an airtanker mission profile, nor is the USAF. I talked to the FAA guy who was on all the calls with the USFS about this program and he was in disbelief when they finally made the decision not to have any FAA involvement.

Over the last year the U.S. Forest Service has awarded or solicited for at least five contracts for conversion and maintenance of the 15 C-23B aircraft that were authorized to be transferred from the U.S. Army to the USFS by legislation signed in December of 2013. The C-23B is the military version of the Shorts 360 (also known as a Sherpa and SD3-60). The USFS plans to use these aircraft to replace all of the USFS owned and contracted aircraft used for smokejumping except for two agency-owned DeHavilland DHC-6 Twin Otters that will be retained for backcountry operations.

The information below is from the U.S. Forest Service, and addresses the use of the 15 C-23B aircraft that were authorized to be transferred from the U.S. Army to the USFS by legislation signed in December of 2013. Unsurprisingly, the agency still has not made “final decisions” on what exactly they will do with the aircraft a year and a half later. I think we’ll coin a new phrase: Paralysis by Lack of Analysis.
“Final decisions have not yet been made, but initial indications are that ten of the C-23B+/SD3-60s will be used to replace all of the Forest Service owned and contracted aircraft used for smokejumping except two agency-owned DeHavilland DHC-6 Twin Otters that will be retained for backcountry operations. Consequently, the future Forest Service smokejumper fleet will consist of two aircraft models – the C-23B+/SD3-60s and the De Havilland DHC-6 Twin Otters.
The Forest Service currently owns a total of 7 aircraft to transport smokejumpers, including 4 Short Brothers C-23As; 2 De Havilland DHC-6 Twin Otters; and 1 Douglas DC-3 TP turbine aircraft. The agency currently contracts for a total of 5 aircraft to transport smokejumpers, including 2 Dornier D0228s; 2 De Havilland DHC-6 Twin Otters; and 1 Casa 212 for smokejumper operations.
Decisions regarding exact placement of individual aircraft will be made by each Forest Service Region according to their operational needs. The current planning is to replace existing aircraft on a one-for-one basis except for DC-3’s which could possibly be replaced on 2 to 1 ratio for additional lift capability.
Operations and Maintenance
The Forest Service will own all of the Shorts C-23B+/SD3-60 Sherpa aircraft. The agency has chosen a Government Owned-Mixed Operations (GOMO) model for this fleet. This means that some will be operated by Forest Service pilots and others will be operated by private industry under contract. The aircraft will also be maintained under a GOMO model with contractor and agency maintenance. The GOMO model will enable the Forest Service to retain a qualified pool of experts in the smokejumper mission who can help ensure that contract pilots operate the government owned aircraft safely and effectively.
The Forest Service is working to minimize the impacts of this transition on agency and contractor employed pilots as much as possible. Existing Forest Service pilots will be retained as active crewmembers in order to maintain a high level of mission standardization, oversight, and quality assurance for the program. Forest Service pilots will be blended with contractors in most missions. Agency and contract pilots will serve as second-in-command until they achieve agency captain rating for the C-23B+/SD3-60 aircraft.
The Forest Service will issue contract solicitations for operation and maintenance services sometime in Fiscal Year 2015, which began October 1, 2014, to be ready for operations in Fiscal Year 2016, which begins October 1, 2015.”
They argue that it is no longer a DC-3 and became a BT-67 when new engines were installed, but retired pilots Barry Hicks and Dick Hulla feel strongly that the last DC-3 the U.S. Forest Service still uses for transporting smokejumpers is not too old at the age of 70 and should not be retired. This is scheduled to be the last fire season for the last remaining DC-3 in the USFS fleet. In an article in the Missoulian, Mr. Hulla said, “It’s going to be flying for 50 years.”
Below is an excerpt from the article:
…Hulla and Hicks argue that while Jump 15 was built in 1945 and has been flying for 18,800 hours, its critical parts are just 5,800 hours old. That makes it younger than most of the other smokejumper aircraft currently in service.
And they add that its larger passenger capacity, stronger airframe and longer flying range make it a better choice than the more recently built Sherpa paratrooper planes the Forest Service plans to replace Jump 15 with.
The two Missoula men bring some extensive credentials to the table. Hulla retired in 2008 as the supervisory pilot for Forest Service Region 1 after a career jumping out of and then flying the BT-67.
Hicks retired in 2003 as regional aviation officer for the Forest Service, with a smokejumping career that goes back to the Ford Tri-motor…
The USFS intends to use some of the fifteen C-23B Sherpa aircraft they recently acquired from the Army to replace the DC-3 and the four C-23As they have had for a while. Compared to the C-23A, the C-23B has a rear cargo ramp that can be opened during flight, inward-opening paratroop doors, and stronger landing gear.
