Loss of Power on Takeoff
in General Tech Discussion
10 years ago
Good morning, two weeks ago went for a 45 minute flight in a 2009 LSA with a 100 horsepower Rotax. After deciding to go flying again and after a 5 to 10 minute delayed taxi, we took off and experienced a loss of power and vibration as the plane just started to become airborne. Aborted takeoff, did 4 to 5 runups getting the temperatures of the engine quite high (just hitting redlines, cyl 285F). We took off and experienced a second loss of power, again at rotation speed. This time maintained power through two losses of power and vibrations and aborted takeoff.
Notes:
Tanks were sumped and clear of water prior to first 45 minute flight and after.
MoGas has been solely used in the airplane for last 22 hours. (TTAFE 134 hrs)
Discussion has been possible vapor lock, no return system on fuel. (all metal air frame low wing, sport cruiser)
Five year hose replacement was done at 88 hours and possible chards in carburetors. Very emphatically I was told you will find debris in carburetor from hose kit.
Plan right now is to remove carburetors and rebuild using local aviation Rotax mechanics.
Any help you can offer will be appreciated. Plane is currently in Santa Monica.
