C-5 brake fire Accident Investigation Board complete

  • Published
Air Mobility Command today released the results of its investigation into the Nov. 2 C-5 aircraft brake fire mishap at Dover Air Force Base, Del.

An Accident Investigation Board, convened by AMC, determined that human error caused the mishap. The C-5 landed at 11:20 p.m. using a visual approach to the runway. According to the report, improper training or misapplication of a technique led to one of the pilots deciding to use a partial flap setting (40 percent) in a landing with an airplane well above normal landing weight.

Additionally, the crew experienced minor problems putting the number two throttle into reverse and deploying the ground spoilers. Because of the time delay in doing these two actions after landing, the pilot was forced to use moderate to heavy braking to bring the C-5 to a safe taxi speed on the remaining runway. After taxiing to the parking area, a crew member discovered a brake fire in the number two main landing gear and proceeded to extinguish it, with help from the Dover AFB Fire/Rescue services.

The AIB also determined three other factors contributed to the mishap:
- Lack of comprehensive training on partial flap landings, specifically under heavy weight conditions, unnecessarily narrowed the safety margin for the landing;
- The wheel spin-up detection system delayed the spoiler deployment, causing the pilot to apply greater than planned braking applications; and
- The crew's desire to land and take off quickly at Dover AFB led them to improperly plan and react to the conditions encountered upon landing.

The 12 crew members and 74 passengers aboard the C-5 were uninjured in the mishap.

The aircraft was assigned to and flown by members of the 433rd Airlift Wing, a reserve associate unit at Lackland Air Force Base, Texas, and was bound for Brasilia, Brazil. It was carrying the passengers and 143,000 pounds of cargo from Andrews Air Force Base, Md.
