Part of a thrust reverser fell off a DC-10 flying from Minneapolis-St. Paul International airport to Honolulu and landed about 100 yards from a home.
Thrust reversers help slow planes as they come in to land. Elizabeth Isham Cory, a spokeswoman for the FAA, said that the 200 lb. part was an "extra mechanism."
No one was injured and the landing was routine. The FAA expects its investigation to last several weeks.
The crew did not notice the missing part until after landing.
