AS 350B Compressor Damaged
Pilot was taking off from base, reported hearing odd whining from engine during takeoff and power changes. Aborted takeoff and returned to staging area. Opened engine cowl, noted aluminum shavings on engine deck. Visual inspection identified the compressor wash union Part Number (P/N) 350A54-1112-20 welded boss on intake assembly P/N 350A54-1080-04 had broken off and become ingested into the engine. Aircraft had been subject to scheduled inspection less than 10 hours prior, with no defects noted at that time. Aluminum shavings from welded boss were found ejected out of the bleed valve and out of the exhaust. The steel union did not get ingested, but bounced around in the intake plenum causing substantial damage to the axial compressor.
Anti ice Fuel Filter Leak
During an aircraft ground run, while performing a leak check on the aircraft, the AME discovered a fuel leak coming from the fuel cap location and discovered that the leak was from the transmission deck. The fuel line hose was found cut from the fitting and spraying fuel inside the transmission compartment.
The ground run was discontinued and the fuel hose replaced.
Transport Canada Comments:
Vigilance during leak checks pays off.
