What US aircraft is this part from?

[gr1974]

Hi, this photo is from another site but I'm hoping that someone may know what aircraft this part is from. It's a crashed US aircraft in PNG. The person is asking for help in identifying the type of aircraft.
Part number 29804-130 with the word
BOHNALITE underneath the numbers.
Thanks in advance.
