Narrative:

The lineman was on light duty and wouldn't/couldn't pull aircraft out of hangar with me. With the aircraft sloped within hangar and too heavy to push out of a wide mouthed t- hangar, I thought it ok to taxi it out to the fuel pump prior to flight. Careful not to hit wingtips (hangar rash) I taxied slowly out, only to knock off 2 inches off wood propeller on hangar support beam. Of course, now it fit nicely through opening, but at that point a normal shutdown was executed. (Subsequent inspection of engine/aircraft showed no damage and returned to service with new propeller.) very rarely do you have to worry about overhead obstacles in this business. One old timer said, after the fact, 'we've lost several other propellers that way, I wouldn't have tried that.' I'll take that under advisement.

Original NASA ASRS Text

Title: PLT OF AN SMA BIPLANE STRUCK THE PROP DURING ATTEMPTED TAXI OUT OF HANGAR.

Narrative: THE LINEMAN WAS ON LIGHT DUTY AND WOULDN'T/COULDN'T PULL ACFT OUT OF HANGAR WITH ME. WITH THE ACFT SLOPED WITHIN HANGAR AND TOO HVY TO PUSH OUT OF A WIDE MOUTHED T- HANGAR, I THOUGHT IT OK TO TAXI IT OUT TO THE FUEL PUMP PRIOR TO FLT. CAREFUL NOT TO HIT WINGTIPS (HANGAR RASH) I TAXIED SLOWLY OUT, ONLY TO KNOCK OFF 2 INCHES OFF WOOD PROP ON HANGAR SUPPORT BEAM. OF COURSE, NOW IT FIT NICELY THROUGH OPENING, BUT AT THAT POINT A NORMAL SHUTDOWN WAS EXECUTED. (SUBSEQUENT INSPECTION OF ENG/ACFT SHOWED NO DAMAGE AND RETURNED TO SVC WITH NEW PROP.) VERY RARELY DO YOU HAVE TO WORRY ABOUT OVERHEAD OBSTACLES IN THIS BUSINESS. ONE OLD TIMER SAID, AFTER THE FACT, 'WE'VE LOST SEVERAL OTHER PROPS THAT WAY, I WOULDN'T HAVE TRIED THAT.' I'LL TAKE THAT UNDER ADVISEMENT.
