Narrative:

Upon completion of the above practice, a steep descent to 3000 ft was effected and a practice ILS approach to runway 4 at 7a1 was made. During this practice approach, greer approach control released aircraft to unicom frequency. In final descent to landing, gradual power reductions were made to control speed and rate of descent. During all phases of this flight until crossing the runway end, conditions were normal. After crossing the runway end, another power reduction was made. Evidently this power reduction, inadvertently, exceeded the limit where aircraft could remain flying and a harder than normal landing was effected. Upon rollout, no vibration was detected, no damage was noted. This lack of any indication of any problem continued through a taxi to the takeoff end of runway 4, a takeoff from runway 4, a second landing on runway 4, a taxi to the end of runway 4 and a takeoff from runway 22. After takeoff from runway 22 a VFR flight was made with a full stop landing at spa. Contact was maintained with greer approach during this flight and all conditions were normal. After landing at spa, propeller tipping on the right propeller was found. One day later the right strut was found to be leaking and 3 days later some skin wrinkling was discovered on the right wing and lower body. At this time the insurance carrier was notified. On jul/xx/94 a repair quotation was received from aviation citing structural damage. In compliance with NTSB 830 the FAA was notified at XA15 local time jul/xx/94 of the incident. No injuries, fatalities, or damage to other property occurred during this incident. Prior to receiving this quotation, did not have the expertise or the confirming data to declare that the damage to aircraft was significant and serious.

Title: PLT OF A CPR SMT TWIN TURBO PROP MADE A 'HARD' LNDG CAUSING DAMAGE TO THE FUSELAGE, WING AND PROP.

Narrative: UPON COMPLETION OF THE ABOVE PRACTICE, A STEEP DSCNT TO 3000 FT WAS EFFECTED AND A PRACTICE ILS APCH TO RWY 4 AT 7A1 WAS MADE. DURING THIS PRACTICE APCH, GREER APCH CTL RELEASED ACFT TO UNICOM FREQ. IN FINAL DSCNT TO LNDG, GRADUAL PWR REDUCTIONS WERE MADE TO CTL SPD AND RATE OF DSCNT. DURING ALL PHASES OF THIS FLT UNTIL XING THE RWY END, CONDITIONS WERE NORMAL. AFTER XING THE RWY END, ANOTHER PWR REDUCTION WAS MADE. EVIDENTLY THIS PWR REDUCTION, INADVERTENTLY, EXCEEDED THE LIMIT WHERE ACFT COULD REMAIN FLYING AND A HARDER THAN NORMAL LNDG WAS EFFECTED. UPON ROLLOUT, NO VIBRATION WAS DETECTED, NO DAMAGE WAS NOTED. THIS LACK OF ANY INDICATION OF ANY PROB CONTINUED THROUGH A TAXI TO THE TKOF END OF RWY 4, A TKOF FROM RWY 4, A SECOND LNDG ON RWY 4, A TAXI TO THE END OF RWY 4 AND A TKOF FROM RWY 22. AFTER TKOF FROM RWY 22 A VFR FLT WAS MADE WITH A FULL STOP LNDG AT SPA. CONTACT WAS MAINTAINED WITH GREER APCH DURING THIS FLT AND ALL CONDITIONS WERE NORMAL. AFTER LNDG AT SPA, PROP TIPPING ON THE R PROP WAS FOUND. ONE DAY LATER THE R STRUT WAS FOUND TO BE LEAKING AND 3 DAYS LATER SOME SKIN WRINKLING WAS DISCOVERED ON THE R WING AND LOWER BODY. AT THIS TIME THE INSURANCE CARRIER WAS NOTIFIED. ON JUL/XX/94 A REPAIR QUOTATION WAS RECEIVED FROM AVIATION CITING STRUCTURAL DAMAGE. IN COMPLIANCE WITH NTSB 830 THE FAA WAS NOTIFIED AT XA15 LCL TIME JUL/XX/94 OF THE INCIDENT. NO INJURIES, FATALITIES, OR DAMAGE TO OTHER PROPERTY OCCURRED DURING THIS INCIDENT. PRIOR TO RECEIVING THIS QUOTATION, DID NOT HAVE THE EXPERTISE OR THE CONFIRMING DATA TO DECLARE THAT THE DAMAGE TO ACFT WAS SIGNIFICANT AND SERIOUS.
