A four-engine air tanker, an L-188, struck a tree while making a retardant drop on a fire August 23, 2020. The tanker was working out of the retardant base at the Chico, California airport and landed safely with no injuries.

There was damage to the leading edge of the left outboard wing, lower outboard wing planks, left inboard flap leading and trailing edge, as well as scuff marks (but no damage) to the #1 prop. The pilots said they knew the drop was low, observed trees near wing level, but were not aware there was a tree strike until mechanics called the damage to their attention after they landed.

In 2019 an L-188 had to execute a belly landing when the crew was not able to get the landing gear down and locked. There were no injuries.

Below is the full text of the “Narrative” and “Corrective Action”  sections as published on SAFECOM about the tree strike:


NARRATIVE

On bombing run on fire BTU Complex, aircraft entered smoke on short final, dropped load, and exiting the smoke observed trees near wing level. Aircraft climbed away with no indication to the pilots of any contact with trees. Aircraft then proceeded with a second run to drop remaining 50% load without incident, was released from the fire and returned to Chico. Flight crew had no indication of tree strike during flight. Evidence of tree strikes to the left wing discovered by maintenance during post flight inspection.

CORRECTIVE ACTION

Aviation Safety Comments: This was the third drop of the day in the same area for this airtanker. The crew reported slowly deteriorating visibility for them in the area due to smoke. On this run an S2T airtanker dropped before them, and when the ATGS asked for them to tag-and-extend the crew stated that they could not see it from their position in the orbit. The ATGS then vectored them in for the drop. They successfully maneuvered onto the final leg and were cleared to drop.

Midway through the drop the airtanker briefly passed through a column of smoke, and when they emerged they immediately saw they were low. They quickly pulled up, stopped the drop, and returned to orbit altitude. They reported not to hear, see or feel any tree strike.

The ATGS had noticed the sudden pull-up maneuver and asked the crew if they were ok and if they had completed the drop. The crew stated all was ok and that they still had a half-load. Noting they were lower than intended on the previous drop, the captain opted to carry more power into the second drop, and conducted it with no issues. The ATGS then asked if they felt their visibility was continuing to deteriorate. Upon confirming it was, the ATGS opted to release them back to base. (Note: The ATGS continued to operate in the area with the S2T for a few more drops).

The crew landed back at base with no issues and left the aircraft. A short time after, they were called by maintenance back to the aircraft, which was the first time they were made aware of the tree strike. There was damage to the leading edge of the left outboard wing, lower outboard wing planks, left inboard flap leading and trailing edge, as well as scuff marks (but no damage) to the #1 prop.

Contributing Factors/Corrective Actions:

This crew is an experienced Canadian airtanker crew on their first day conducting aerial firefighting missions in California. A comment made by the captain was that his ‘muscle memory’ for power settings during drops had yet to account for the increased heat in CA. He realized after the low drop that that may have been a factor, and corrected by carrying more power into the subsequent drop, which he felt resulted in a normal height pass. This will be a talking point with subsequent Canadian crews that may come to California during this fire season.

Additionally, the aircraft Radar Altimeter appeared to not be functioning, which could have provided them with more situational awareness as they passed through the column of smoke on the drop. Before the aircraft is returned to service, the Radar Altimeter will be checked for functionality.

Lastly, a general sense during discussion with the crew is that they felt the smoke visibility in the area may have added an additional challenge as they acclimated to not only the environment, but also to CAL FIRE aerial firefighting operations (ex: FTA operations).

Additional training for visiting Canadian crews will be to emphasize that we not only hope that they feel comfortable in declining missions or drops they don’t feel can be conducted safely, we expect it.

Air tanker makes emergency wheels-up landing at Red Deer, Alberta

The landing was caught on video

Tanker 490, an L-188, made an emergency landing June 22, 2019 at Red Deer Regional Airport when it had problems with the landing gear. Screenshot from the video below just before it touched down on the runway.

One of Air Spray’s four-engine L-188 Electras had a problem with its landing gear June 22 and had to make an emergency wheels-up landing at Red Deer Regional Airport in Alberta.

Red Deer News Now reported that according to Graham Ingham, CEO at the airport, the incident happened around 12:20 p.m.

“We had an Air Spray air tanker, an Electra-type aircraft, perform an emergency landing due to the fact it couldn’t get its main landing gear down. After a couple of attempts, they decided that it would be safer to do a wheels up landing, and subsequently they did. Thankfully they came to a complete stop. There were no injuries, no fire and it was the best outcome for everyone.”

Mr. Ingham said two pilots and two other people on board walked away from Air Tanker 490 without any injuries.

The video below shows what looks like an excellent landing, considering the circumstances.

The cause of the landing gear problem has not been released.

Other firefighting aircraft have had landing gear problems:

Air tankers working the Chuckegg Creek Fire in Alberta

The large aircraft on the left is the Electra L-188. It has four turbine engines, can cruise at 592 km/hr (368 mph), and can carry 11,365 liters (3,000 gallons) of fire retardant.

To the right of the Electra are four of the Air Tractor 802F amphibious aircraft. They can work as land-based or skimmer air tankers. They have a cruising speed of 260 km/hr (161 mph) and can carry up to 2,430 liters (644 gallons).

The Chuckegg Creek Fire in northern Alberta has burned 276,000 hectares (682,000 acres).

Two large air tankers in Canada were recently certified and are ready for fire assignments.

Buffalo Airways has a newly certified L-188, Tanker 416. We asked Raquel Downey of Buffalo about the smoke or dust visible in the picture under and behind the aircraft. She said it was “just dust and dirt being blown back”. It must have been on a dirt or gravel runway.

We also asked Ms. Downey about the status of the P3 they purchased two years ago, but she said Joe McBryan is not answering any questions about the aircraft. We heard from a reliable source in March that it was in Florida getting some maintenance done.

And Air Spray’s Tanker 492 received the last of its FAA and Transport Canada certifications over the weekend. It rolled out of the hangar today and straight into service in Alberta, Canada. It has an updated RADS II tank and a new paint job.

Congrats to Buffalo and Air Spray.

Slow-motion video of Lockheed Electra L-188 retardant drops

A Lockheed Electra L-188 air tanker, #489, dropping in slow motion on a wildfire. The date, location, and videographer (other than the logo at bottom-right) are unknown.

The wake turbulence as the aircraft passes through the smoke at 2:45 is very interesting, as is the precision drop at 1:45, keeping the retardant off the rocks in an area that is highly visible to recreationists on the nearby lake.

In August of 2012 Wildfire Today ran a photo of Tanker 489 dropping on the Taylor Bridge Fire.

Air Spray to begin converting a second BAe-146

Following up on the development that Air Spray has received a Call When Needed contract from CAL FIRE for an L-188 Electra, we checked with Ravi Saip, Air Spray’s Director of Maintenance and General Manager at their new Chico facility in California to get an update on their conversion of a BAe-146 into an air tanker. Like some of the aviation companies, they are keeping their cards close to the vest, but he told us that the project is “moving along well”, and they “anticipate being available for the 2014 fire season”. They have a second BAe-146 that will be “arriving soon” which will also will be converted.

Mr. Saip said, “The long term goal for Air Spray is to facilitate the needs of both the US and Canadian wildfire management teams with as many tools as they need.”

Air Spray signs contract with CAL FIRE

Air Spray, an air tanker company with headquarters in Red Deer, Alberta, Canada, has received a Call When Needed contract from CAL FIRE for an L-188 Electra “Long Liner” air tanker. The company flew Tanker 482 down to California last week, Chico and later McClennan, to get the aircraft and pilots carded by CAL FIRE. The flight crew will be evaluated by CAL FIRE this week.

Air Spray will leave the L-188 at Chico until the weather turns, and when activated on the CWN contract, they will fly a crew down from Red Deer. They may add up to three more L-188s to the contract when the air tankers are released from their Canadian contracts.

Air Spray also operates Turbo Commander 690 “Bird Dogs” or lead planes, as well as some charter aircraft.

The L-188’s air frame is virtually the same as the P-3, a maritime patrol aircraft which has also seen service in its later years as an air tanker; the L-188 has been called a P-3 with windows. Both of them carry about 3,000 gallons of retardant.

Last year Air Spray established a new United States base at Chico and announced that they had acquired a BAe-146 airliner which they would convert into an air tanker in the new facility.

They hired several workers who had previously worked for the now bankrupt Aero Union. Seven of Aero Union’s P-3 air tankers have been parked at McClellan for over a year, with an eighth in Canada. They are still owned by the bank, unsold, due to the very high cost of putting them back into flyable shape. The rumors that the P-3s have been scrapped are not true.

 

Thanks go out to Johnny, Walt, and Jerome.
