Narrative:

As captain, I landed the aircraft using normal procedures. Nothing unusual was noted by myself or the first officer, and no unusual impact or sounds were reported by the rest of the crew. Sometime later, a maintenance inspection discovered that both reversers had at some time contacted the runway. The flight data recorder appears to indicate that the contact occurred on this landing. To the best of my knowledge, I did not reverse the engines with a high deck angle, but it is difficult to argue with a flight data recorder trace. Callback conversation with reporter revealed the following information: the reporting first officer states that both reverser doors were scraped on the runway on deployment. The doors extend in an arc, going further down while in transit than they are when in the reverse position. The reporting first officer inspected the aircraft on his next walk around and found nothing, as did the next crew. The third crew found the scrape. The damage was laid to the reporting crew by checking the flight data recorder and finding that the reporting crew was the only one that had deployed their reversers at a high deck angle. Both crew men were given a takeoff and landing period in the simulator. The air carrier replaced both reverser doors. There has been no action by the FAA. The reporting crew had no inclination that they had caused any damage. The air carrier did not notify the crew of this for about a week. Supplemental information from acn 247920: backtracking on the flight data recorder appears to indicate the damage happened on this landing. Was not notified of any damage till aug/wed/93.

Title: AN ACR MLG CREW SCRAPED BOTH OF ITS LOWER THRUST REVERSER DOORS ON LNDG.

Narrative: AS CAPT, I LANDED THE ACFT USING NORMAL PROCS. NOTHING UNUSUAL WAS NOTED BY MYSELF OR THE FO, AND NO UNUSUAL IMPACT OR SOUNDS WERE RPTED BY THE REST OF THE CREW. SOMETIME LATER, A MAINT INSPECTION DISCOVERED THAT BOTH REVERSERS HAD AT SOME TIME CONTACTED THE RWY. THE FLT DATA RECORDER APPEARS TO INDICATE THAT THE CONTACT OCCURRED ON THIS LNDG. TO THE BEST OF MY KNOWLEDGE, I DID NOT REVERSE THE ENGS WITH A HIGH DECK ANGLE, BUT IT IS DIFFICULT TO ARGUE WITH A FLT DATA RECORDER TRACE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTING FO STATES THAT BOTH REVERSER DOORS WERE SCRAPED ON THE RWY ON DEPLOYMENT. THE DOORS EXTEND IN AN ARC, GOING FURTHER DOWN WHILE IN TRANSIT THAN THEY ARE WHEN IN THE REVERSE POS. THE RPTING FO INSPECTED THE ACFT ON HIS NEXT WALK AROUND AND FOUND NOTHING, AS DID THE NEXT CREW. THE THIRD CREW FOUND THE SCRAPE. THE DAMAGE WAS LAID TO THE RPTING CREW BY CHKING THE FLT DATA RECORDER AND FINDING THAT THE RPTING CREW WAS THE ONLY ONE THAT HAD DEPLOYED THEIR REVERSERS AT A HIGH DECK ANGLE. BOTH CREW MEN WERE GIVEN A TKOF AND LNDG PERIOD IN THE SIMULATOR. THE ACR REPLACED BOTH REVERSER DOORS. THERE HAS BEEN NO ACTION BY THE FAA. THE RPTING CREW HAD NO INCLINATION THAT THEY HAD CAUSED ANY DAMAGE. THE ACR DID NOT NOTIFY THE CREW OF THIS FOR ABOUT A WK. SUPPLEMENTAL INFO FROM ACN 247920: BACKTRACKING ON THE FLT DATA RECORDER APPEARS TO INDICATE THE DAMAGE HAPPENED ON THIS LNDG. WAS NOT NOTIFIED OF ANY DAMAGE TILL AUG/WED/93.
