It is not unknown for parts from crashed aircraft to be reused.
The following text is taken from a Wikipedia thread concerning part from the L1011 that crashed in the Everglades.
Over the following months and years, employees of Eastern Air Lines began reporting sightings of the dead crew members, captain Robert Loft and second officer (flight engineer) Donald Repo, sitting on board other L-1011 (N318EA) flights.[32][33][34]
Parts of Flight 401 were salvaged after the crash investigation and refitted into other L-1011s.[32][35] The reported hauntings were only seen on the planes that used the spare parts.[32][33] Sightings of the spirits of Don Repo and Bob Loft spread throughout Eastern Air Lines to the point where Eastern's management warned employees that they could face dismissal if caught spreading ghost stories.[33]
While Eastern Airlines publicly denied some of their planes were haunted, they reportedly removed all the salvaged parts from their L-1011 fleet.[34] Over time, the reporting of ghost sightings stopped. An original floor board from Flight 401 remains in the archives at History Miami in South Florida.[36]
Eastern Air Lines CEO (and former Apollo astronaut) Frank Borman called the ghost stories surrounding the crash "garbage".[37]
