Narrative:

Small aircraft was released to owner 12/xx/91 after prolonged maintenance period for air frame modifications and major overhaul of pwrplant. Takeoff after normal runup at W00 plus 3 hours at cruise (greater than 80 percent per overhauler recommendations) was uneventful. Entered right pattern for 32 at gai in landing confign at approximately 2000 FPM. Initiated descent at numbers abeam on downwind. Power failure at 1800- 1500 RPM. Unable to restart. Cleaned up and turned toward runway, advising intentions on unicom. Deployed gear immediately prior to hard landing on edge of runway. Damage to aircraft cosmetic -- gear doors, skin damage right wingtip/aileron, pilot with minor contusions. Subsequent engine inspection revealed faulty (new) seal in injector servo. Aircraft under repair at time of this report. I was owner/pilot on this flight.

Title: GA SMA FAILURE IN TFC PATTERN AT THE END OF A 3 HR RUN INFLT.

Narrative: SMA WAS RELEASED TO OWNER 12/XX/91 AFTER PROLONGED MAINT PERIOD FOR AIR FRAME MODIFICATIONS AND MAJOR OVERHAUL OF PWRPLANT. TKOF AFTER NORMAL RUNUP AT W00 PLUS 3 HRS AT CRUISE (GREATER THAN 80 PERCENT PER OVERHAULER RECOMMENDATIONS) WAS UNEVENTFUL. ENTERED R PATTERN FOR 32 AT GAI IN LNDG CONFIGN AT APPROX 2000 FPM. INITIATED DSCNT AT NUMBERS ABEAM ON DOWNWIND. PWR FAILURE AT 1800- 1500 RPM. UNABLE TO RESTART. CLEANED UP AND TURNED TOWARD RWY, ADVISING INTENTIONS ON UNICOM. DEPLOYED GEAR IMMEDIATELY PRIOR TO HARD LNDG ON EDGE OF RWY. DAMAGE TO ACFT COSMETIC -- GEAR DOORS, SKIN DAMAGE R WINGTIP/AILERON, PLT WITH MINOR CONTUSIONS. SUBSEQUENT ENG INSPECTION REVEALED FAULTY (NEW) SEAL IN INJECTOR SERVO. ACFT UNDER REPAIR AT TIME OF THIS RPT. I WAS OWNER/PLT ON THIS FLT.
