I had just purchased the aircraft. I performed numerous inspections and preflts. The display bombs and shackles appeared to be securely fastened to the aircraft. Upon arrival at our destination I noticed that bomb and shackle had departed the aircraft. In the future, I feel that the shackles and/or bombs should be safety wired or pinned to the aircraft. Callback conversation with reporter revealed the following information: reporter states that the display bombs were safety wired to the shackles, but the lock nuts on the shackles had been loosened which allowed them to back off in flight and drop the entire unit shortly after departure. It was found the next day next to a road in a rural area. No injuries. The aircraft was a grumman C1A, an ex-navy aircraft which reporter will use in air shows. The FAA came by to see what happened and were very impressed with reporter's operation. No further action. Reporter collects aircraft and has full time a&P and a very clean operation.

Title: GRUMMAN C1A PLT LOSES DISPLAY BOMB AND SHACKLE OFF AN ACFT SHORTLY AFTER TKOF.
Narrative: I HAD JUST PURCHASED THE ACFT. I PERFORMED NUMEROUS INSPECTIONS AND PREFLTS. THE DISPLAY BOMBS AND SHACKLES APPEARED TO BE SECURELY FASTENED TO THE ACFT. UPON ARR AT OUR DEST I NOTICED THAT BOMB AND SHACKLE HAD DEPARTED THE ACFT. IN THE FUTURE, I FEEL THAT THE SHACKLES AND/OR BOMBS SHOULD BE SAFETY WIRED OR PINNED TO THE ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT THE DISPLAY BOMBS WERE SAFETY WIRED TO THE SHACKLES, BUT THE LOCK NUTS ON THE SHACKLES HAD BEEN LOOSENED WHICH ALLOWED THEM TO BACK OFF IN FLT AND DROP THE ENTIRE UNIT SHORTLY AFTER DEP. IT WAS FOUND THE NEXT DAY NEXT TO A ROAD IN A RURAL AREA. NO INJURIES. THE ACFT WAS A GRUMMAN C1A, AN EX-NAVY ACFT WHICH RPTR WILL USE IN AIR SHOWS. THE FAA CAME BY TO SEE WHAT HAPPENED AND WERE VERY IMPRESSED WITH RPTR'S OP. NO FURTHER ACTION. RPTR COLLECTS ACFT AND HAS FULL TIME A&P AND A VERY CLEAN OP.
