Five of the 18 aircraft grounded July 17 have been repaired
Five of the 18 grounded C-5M aircraft at Dover Air Force Base have taken to the air again following repairs to their landing gear.
Air Mobility Command commander Gen. Carleton D. Everhart II on July 17 ordered the stand down after two landing gear malfunctions occurred two Dover Galaxy aircraft within a 60-day period.
Both took place at Rota Naval Air Station, Spain.
On Aug. 1, Everhart released those five aircraft but said the remaining 13 would remain on stand down pending successful completion of testing, repairs, and evaluation of the nose gear.
During the stand-down, Dover maintainers conducted extensive C-5M nose
landing gear inspections to identify, analyze and repair the issue.
According to an AMC press release, the problem was traced to what is known as ball screw assembly in the nose landing gear.
According to an article on the military.com website, the gears operate in tandem to extend or retract the nose gear.
In the July 27 article, Everhart was quoted as saying the gear was being worn out by heavy use of the aircraft in worldwide missions. A failure in one of the two can cause the landing gear to stall either when it’s being extended or retracted, according to an AMC spokesman.
According to Everhart, the necessary parts are no longer manufactured, meaning replacements must come from supplies on hand or taken from other aircraft. Faulty parts will be sent to an Air Force repair facility in Utah to be refurbished.
Although the C-5Ms have been upgraded with new engines and avionics, they’ve been in use at Dover longer than other bases meaning they’ve seen more missions which have led to more stress on the aircraft.
436th Airlift Wing Commander Col. Ethan Griffin said maintenance personnel from both the 436th and the US Air Force Reserve 512th Airlift Wing worked with experts from other bases to fix the problem.
“Our maintainers, aircrew and safety personnel are absolutely committed to delivering excellence and Dover pride while ensuring the continued viability of the C-5M enterprise and Rapid Global Mobility for our nation’s defense,” he said.
The maintenance crews were comprised of more than 200 active duty, Reserve and civilians as well as engineers from Robins AFB, Georgia, and the Ogden Air Logistics Complex at Hill AFB, Utah
Maintenance airmen from the Air Force’s three other C-5 bases traveled to
Dover to learn the processes undertaken at the base to become proficient at these inspections so they could complete inspections on their own C-5 fleets.
These bases are Travis AFB, California; Westover Air Reserve Base, Massachusetts;
and Joint Base San Antonio-Lackland, Texas.
