## Discrepancy

HONDAJET N909BP, 42000099, TAXIED OUT ON SUNDAY, AUGUST 2, AND THE LINE SERVICE PERSONNEL FOUND A 7" X 2" CURVED STAINLESS-STEEL PLATE/PIECE WITH P/N - 4JQT4-13121-Q0A-0100 LAYING ON THE GROUND WHERE THE AIRCRAFT HAD PARKED. A SECUITY VIDEO SHOWED AN OBJECT BEING EJECTED FROM THE EXHAUST PATH OF THE RIGHT ENGINE. HONDAJET TECH SUPPORT CONFIRMED THAT THIS WAS ONE OF THE "GG CASE BOLT COVERS", ONE OF 6 TOTAL PER ENGINE. HONDAJET TECH SUPPORT FURTHER STATED THAT THESE COVERS HAD BEEN FOUND MISSING AND/OR BROKEN IN SEVEREAL ENGINES THAT HAD BEEN REMOVED FOR OTHER MAINTENANCE (POSSIBLY LOSING THEIR COVERS IN FLIGHT), AND ONLY ONE OTHER COVER HAD BEEN FOUND FROM AN OPERATIONAL AIRCRAFT. A BORSCOPE INSPECTION OF BOTH ENGINES ON 42000099 WAS ACCOMPLISHED, VERIFYING THAT ONE COMPLETE COVER WAS MISSING FROM THE RIGHT ENGINE AND THAT ABOUT 25% OF A COVER WAS MISSING FROM THE LEFT ENGINE. HONDAJET AND GE HONDA AERO ENGINES ISSUED A LETTER FOR CONTINUED OPERATION.
