Boeing 747 Air India Flight 182 Essentials Canadian report
Fast and loose with cargo door. Took off late and at night. page 5
FDR hit and jolted or plane went left wing down. Abrupt power cut. page
Sound on CVR not like bomb. page 23
Sound matches explosive decompression of DC-10 caused by opening cargo door.
No bomb; explosive decompression yes. page 24
Inflight damage severe on right side of aircraft. page 26
Right wing fillet inflight damage. page 29 and 30
Engine number 3 fodded, coming apart and fods engine 4. page 29
Wreckage plot, three areas. 1. Nose and wings, 2. Tail. 3. Engines. Three
engines together and one alone near number 3 nacelle strut. page 32
Forward cargo door broken, damaged by outward force, important to retrieve
but lost. page 34
Piece of forward cargo door has evidence of explosive force but no explosion
residue or pitting from bomb. page 41
Could be explosive decompression as initial event. page 47
No fire or explosion in cabin or flight deck areas or on passengers. page
Right side of plane has inflight damage. Fod in engines 3 and 4. Failure
of door would explain many observations. page 49 and 50
Explosion in forward cargo compartment explains observations. Explosive
decompression which occurs when cargo door opens produces explosive effects.
Comment: Report received skewed from Canada and scanned
as received. Observations by investigators are consistent with inadvertent
opening of forward cargo door inflight.
