For more than 15 years Minden Air Corp has been working on the concept of transitioning from their Korean War vintage P2V air tankers to a jet, the BAe-146. They acquired two or three of them and had nearly completed their work on what was going to be Air Tanker 46 when they ran out of money. Problems with hydraulic systems led to landing gear failures on two P2Vs, T-48 and T-55, taking out Minden’s last two operational air tankers, which no doubt affected their incoming revenue stream. Thankfully there were no serious injuries reported in those two accidents, unlike the crash of the company’s T-99 on October 3, 2003 that killed the two pilots, Carl Dolbeare , 54 and John Attardo, 51. A lookout staffing a fire tower saw that P2V fly into a cloud bank as it was preparing to land at San Bernardino. It did not emerge and shortly thereafter they saw what appeared to be smoke at the top of the cloud. The NTSB described it as “controlled flight into mountainous terrain”. The two pilots had a combined total of more than 15,000 flight hours.
In October AvGeek filmed a report about Minden Air Corp at the Minden Airport 45 miles south of Reno, Nevada.
Tim Cristy, Flight Operations for Minden, said in the video when explaining why the conversion of T-46 came to a stop, “We ran out of money. Well, the engineering got expensive as all get-out”.
We attempted to call Mr. Christy and Minden’s CEO, Len Parker, to get more information but the number we had used before no longer works.
The T-46 project had progressed to conducting a grid test, which involves dropping retardant over a grid of more than 3,000 cups on the ground. In the video Mr. Cristy said the test went well. We are not sure if the aircraft ever received a Supplemental Type Certificate from the FAA which is a major hurdle to overcome in addition to approval from the Interagency Airtanker Board. After that they would have had to deal with the bewildering and unpredictable Forest Service contracting system before they ever received a dime from their large monetary investment.
The video below, published June 17, 2014, shows T-46 making its first test drops of water and retardant.

Tim Crippin took these photos of CL-415s and CV-580s at the Medford, Oregon Airport August 1 and 2. Some of them were working on the Bybee Creek Fire in Crater Lake National Park which has burned 720 acres since it started on July 28.
In addition to the Canadian air tankers being assigned to Alaska (seven recently that we know of) there are three air tankers under contract with the U.S. Forest Service in the state, according to information we received from today from Jennifer Jones, a spokesperson for the agency:
T-160 Aero-Flite RJ85
T-10 Neptune BAe-146
T-101 Aero Air MD87

The National Transportation Safety Board probable cause report on the June 3, 2012 crash of Tanker 11 concluded that while preparing to drop retardant on the White Rock fire near the Utah/Nevada state line, the flight crewmembers “did not properly compensate for the wind conditions while maneuvering”. The aircraft impacted the ground before it reached the location for the intended drop, causing the death of pilots Todd Tompkins and Ron Chambless.
A photographer got some pictures of the tanker as it was attempting to make the drop (below). It is likely that the pilots jettisoned the retardant when it became obvious they were too low.
The P2V, operated by Neptune Aviation, was about to make its second drop on the fire that day. Shortly before the crash it made a dry run over the target area, then when lining up for the drop on the next pass took a different path, which was lower, and made a wider right turn, according to the report.
The same day that Tanker 11 crashed, another P2V, Tanker 55 operated by Minden, had a mechanical failure and landed at Minden, Nevada with a main landing gear not fully extended. The aircraft was heavily damaged, but there were no serious injuries. The landing was recorded on video.
On June 26, 2010 air tanker 44, a P2V operated by Neptune Aviation also experienced a hydraulic failure upon landing, had no brakes, and went off the runway at Rocky Mountain Metropolitan Airport (JeffCo) in Colorado (map). Both pilots self-evacuated and were walking around when the fire apparatus arrived to put out a fire in one of the engines. Neptune repaired the aircraft and put it back into service.
The NTSB released a nine-page Factual Report on the crash of Tanker 11. Below is the complete text of the one-page probable cause report, released September 24, 2014:
14 CFR Public Use
Accident occurred Sunday, June 03, 2012 in Modena, UT
Probable Cause Approval Date: 09/24/2014
Aircraft: LOCKHEED P2V-7, registration: N14447
Injuries: 2 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this public aircraft accident report.
Tanker 11 departed the tanker base to conduct its second fire retardant drop of the day in the same location. Upon arriving in the fire traffic area, Tanker 11 followed the lead airplane into the drop zone, which was located in a shallow valley 0.4 mile wide and 350 feet deep. The lead airplane flew a shallow right turn onto final and then dropped to an altitude of 150 feet above the valley floor while approaching the intended drop zone. While making the right turn onto final behind the lead airplane, Tanker 11’s right wing tip collided with terrain, which resulted in a rapid right yaw and subsequent impact with terrain. The wreckage created a 1,088-foot-long debris field, and a postimpact fire ensued.
Two witnesses took photographs of the accident sequence photos, and an examination of these photographs showed that the lead airplane was positioned ahead of the tanker throughout the flight; however, the orientation of the lead airplane compared to the orientation of Tanker 11 indicated that Tanker 11 did not directly follow the lead airplane’s path to the final drop course. Rather, it was about 700 feet left of the lead airplane’s path and made a wider right turn as it attempted to align with the final drop course. The accident flight crewmembers had previously flown nearly the same exact drop and the lead pilot cautioned them about tailwind conditions during the flight; however, the wider turn suggests that they did not properly compensate for the wind conditions while maneuvering. In addition, the previous flight was conducted at an altitude above the ridgeline. GPS evidence indicates that the accident flight was conducted below the ridgeline, which would have made it more difficult to detect the rising terrain during the wider turn. A review of the airplane’s cockpit voice recorder audio information revealed that the flight crew did not recognize or attempt to correct the reduced clearance between Tanker 11 and the rising terrain until about 2 seconds before impact.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The flight crew’s misjudgment of terrain clearance while maneuvering for an aerial application run, which resulted in controlled flight into terrain. Contributing to the accident was the flight crew’s failure to follow the lead airplane’s track and to effectively compensate for the tailwind condition while maneuvering.
