Bullet fired inside aircraft
 

Just say... that a bullet was accidentally fired inside an airliner by a skymarshall and it went into the floor. After hitting a seat. A 9mm bullet from a pistol. In Damascus. This morning. Anyway, lets just SAY that if such a thing HAD happened....
what would the correct engineering procedure be before that aircraft was allowed to fly again?? Thanks

Replace the seat, carpet and repair the floor panel.

However, if the bullet went through the floor panel thats a whole different story. A through inspection would be required, becuse depending where in the aircraft the marshall was, you could have considerable damage, that will take a lot of time to fix. Under the floor there are wires, cables, cargo compartments, fuel tanks, air conditioning ducts and black boxes of all types and functions. Not to mention damage to internal structure and a possable hole in the fuselage.

Assess the damage inform the authorities ie FAA CAA etc contact the manufacturer stating the damage and cause either formulate or ask the manufacturer
for a repair solution carry out the repair then have it assesed for correctness with the repair scheme and release to service.This is assuming that such a repair is not already covered in the SRM(structural repair manual)

Where was the bullet fired from?
Is final position of bullet known?
What was aircraft configuration at time of Incident?

Did any of you see the Mythbusters episode where they pressurized a DC-9 and fired a SIG P226 at and through the sides of the aircraft? They determined that no amount of shooting in any location of the side of the fuselage would cause an explosive decompression great enough to seriously affect the controlllability of the plane.

They had to use FBI explosives to create sizeable hole in the side of the plane. Needless to say, a catastrophic structural failure caused by a 9mm bullet is unlikely, according to their tests.

:) Make an entry in the Cabin Condition Log so the cleaners will know to clean up the brown adrenalin on the seat cushions

Oh, bless the skymarshalls. Really do feel safe with them around, a real gift to aviation, they are.
:E

Aren't they just? :uhoh:

Say.. the bullet was fired from the rearmost row of seats whilst the a/c was on ground, went thru a seat and then thru the floor, cut an emergency brake cable, and penetrated the hold where it stopped.

Sure you can fix the seat, the floor, the cable, the hole etc but what would the official engineering / manufacturer advice be? Anyone?

Bullet fired
 

Now I am not a driver, and only my best friends would call me a genius after I bought them a lot of beer, but it strikes me, " why are you even asking ?"!

The thing needs grounding and a thorough investigation, including functioning everything one can think of and a long chat with the manufacturers.

Might not be popular with the accountants, unless they were part of the cargo, but tough...
