Aircraft was light: fuel at 14 gallons, no cargo. This puts center of gravity near forward limit. Sand bar was rough. After landing, I raised the tail (needed some power to do this). So I could see the taxi path better. Just as I did this, the aircraft rolled into a depression, the nose went down -- full up elevator was no help. The propeller contacted the sand which was soft enough that the spinner did not stop the aircraft. (No brakes were used.) this aircraft, the C model (or spring gear) maule M7 has the center of the mains right at the datum. Consequently after some point there is a quick downward roll of the nose which can't be stopped. Lessons: never fly without enough weight to put center of gravity back somewhat. Will do stc to put weight in tail.
Original NASA ASRS Text
Title: PVT PLT OF A MAULE M7 NOSED UP ON THE PROP DURING TAXI AFTER LNDG DUE TO ATTEMPTING TO TAXI WITH TAIL HIGH FOR SEEING THE TXWY. HOWEVER, THE PLT LOST CTL OF THE ACFT WHEN IT WENT INTO A SANDY DEPRESSION.
Narrative: ACFT WAS LIGHT: FUEL AT 14 GALLONS, NO CARGO. THIS PUTS CTR OF GRAVITY NEAR FORWARD LIMIT. SAND BAR WAS ROUGH. AFTER LNDG, I RAISED THE TAIL (NEEDED SOME PWR TO DO THIS). SO I COULD SEE THE TAXI PATH BETTER. JUST AS I DID THIS, THE ACFT ROLLED INTO A DEPRESSION, THE NOSE WENT DOWN -- FULL UP ELEVATOR WAS NO HELP. THE PROP CONTACTED THE SAND WHICH WAS SOFT ENOUGH THAT THE SPINNER DID NOT STOP THE ACFT. (NO BRAKES WERE USED.) THIS ACFT, THE C MODEL (OR SPRING GEAR) MAULE M7 HAS THE CTR OF THE MAINS RIGHT AT THE DATUM. CONSEQUENTLY AFTER SOME POINT THERE IS A QUICK DOWNWARD ROLL OF THE NOSE WHICH CAN'T BE STOPPED. LESSONS: NEVER FLY WITHOUT ENOUGH WT TO PUT CTR OF GRAVITY BACK SOMEWHAT. WILL DO STC TO PUT WT IN TAIL.
