Narrative:

I selected gear down and added flap. The approach to the field was steeper than normal, therefore, reducing the throttles to zero twice on final approach. No indication of a gear warning horn occurred. Subsequently, a gear up landing occurred. On oct/fri/92, I made a point to go to the club and check that all maintenance and airworthiness were current with the aircraft. After meeting with club officials, it was determined that the aircraft was airworthy. Upon further investigation, I learned that club officers knew of the inoperative gear horn and failed to advise me of the problem. In my opinion, this was a direct result of the FAA's scrutiny with club maintenance and, in an effort to maintain legality, did not 'squawk' the problem (i.e., if it is not written, it doesn't exist). As well, a note was left on the club locker door to only squawk flight urgent matters. 1 last thing that I also found out a few days later was that an eyewitness said he saw the left gear partially extend.

Original NASA ASRS Text

Title: AN SMT MADE A WHEELS UP LNDG. THE LNDG GEAR WARNING SYS WAS INOP.

Narrative: I SELECTED GEAR DOWN AND ADDED FLAP. THE APCH TO THE FIELD WAS STEEPER THAN NORMAL, THEREFORE, REDUCING THE THROTTLES TO ZERO TWICE ON FINAL APCH. NO INDICATION OF A GEAR WARNING HORN OCCURRED. SUBSEQUENTLY, A GEAR UP LNDG OCCURRED. ON OCT/FRI/92, I MADE A POINT TO GO TO THE CLUB AND CHK THAT ALL MAINT AND AIRWORTHINESS WERE CURRENT WITH THE ACFT. AFTER MEETING WITH CLUB OFFICIALS, IT WAS DETERMINED THAT THE ACFT WAS AIRWORTHY. UPON FURTHER INVESTIGATION, I LEARNED THAT CLUB OFFICERS KNEW OF THE INOP GEAR HORN AND FAILED TO ADVISE ME OF THE PROBLEM. IN MY OPINION, THIS WAS A DIRECT RESULT OF THE FAA'S SCRUTINY WITH CLUB MAINT AND, IN AN EFFORT TO MAINTAIN LEGALITY, DID NOT 'SQUAWK' THE PROBLEM (I.E., IF IT IS NOT WRITTEN, IT DOESN'T EXIST). AS WELL, A NOTE WAS LEFT ON THE CLUB LOCKER DOOR TO ONLY SQUAWK FLT URGENT MATTERS. 1 LAST THING THAT I ALSO FOUND OUT A FEW DAYS LATER WAS THAT AN EYEWITNESS SAID HE SAW THE L GEAR PARTIALLY EXTEND.
