What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
An aircraft requested a ferry permit for maintenance after experiencing a battery fire/explosion. The aircraft has significant damage to the fuselage frame forward of the battery compartment, the cabin air tube is disconnected as well as crushed. Fire damage caused multiple lines, cables & hoses to melt and deteriorate therefore, needing evaluation for their serviceability and integrity. Finally it appears an alternate battery was installed without proper documentation, as the log books do not contain both the recent fire damage that occurred and battery installation and there is evidence of exterior empennage damage on both sides, forward of the air scoop.
