Narrative:
Aircraft was on visual approach runway 10L with only the pilot in the plane. Aircraft entered normal flare position at normal speeds and at nose touchdown veered sharply to right and departed runway. No damage or injuries occurred and plane was taxied to the ramp. Thorough inspection and testing of nose strut assembly revealed a possible problem with the nose strut bungee system, but was not totally conclusive. Aircraft was flown back to home base with a ferry permit and maintenance was performed. At touchdown, no brakes were being applied, trim controls were in neutral position and rollout was on the centerline. Pilot feels that nose gear (strut) was sticking out of centerline, combined with excess air pressure in strut, caused situation where rudder inputs were useless on the ground.
Original NASA ASRS Text
Title: SMA PLT LOST CTL OF THE SAME ACFT 2 DAYS IN A ROW. ACFT VEERED TO THE R AFTER NOSEWHEEL TOUCHDOWN. ACFT DEPARTED THE RWY.
Narrative: ACFT WAS ON VISUAL APCH RWY 10L WITH ONLY THE PLT IN THE PLANE. ACFT ENTERED NORMAL FLARE POS AT NORMAL SPDS AND AT NOSE TOUCHDOWN VEERED SHARPLY TO R AND DEPARTED RWY. NO DAMAGE OR INJURIES OCCURRED AND PLANE WAS TAXIED TO THE RAMP. THOROUGH INSPECTION AND TESTING OF NOSE STRUT ASSEMBLY REVEALED A POSSIBLE PROB WITH THE NOSE STRUT BUNGEE SYS, BUT WAS NOT TOTALLY CONCLUSIVE. ACFT WAS FLOWN BACK TO HOME BASE WITH A FERRY PERMIT AND MAINT WAS PERFORMED. AT TOUCHDOWN, NO BRAKES WERE BEING APPLIED, TRIM CTLS WERE IN NEUTRAL POS AND ROLLOUT WAS ON THE CTRLINE. PLT FEELS THAT NOSE GEAR (STRUT) WAS STICKING OUT OF CTRLINE, COMBINED WITH EXCESS AIR PRESSURE IN STRUT, CAUSED SIT WHERE RUDDER INPUTS WERE USELESS ON THE GND.
