Q

Describe a plug type door ?

A

-Seals itself keeping a pressure difference on its two sides ( inside and outside )
-The higher pressure forces door into wedge-shaped door into the frame establishing a seal and preventing it from. Being opened until pressure is released.

38
Q

Whats the two methods to apply sealant to an aircraft’s fuselage ?

A
  1. Faying seal
  2. Fillet seal
39
Q

Whats faying sealant used for ?

A

Two overlapping pieces of metal that are being joined

40
Q

Whats fillet seal used for ?

A

When two pieces of metal are joined together.

41
Q

Where is the attachment point for the landing gear ?

A

Wing spars or framework reached to the spar

42
Q

How can you detect delamination in a cockpit window ?

A

Look at the cockpit from a angle and the delaminated part will appear as a shiny, flat bubble

43
Q

What can bubbles in the vinyl layer indicate ?

A

There is a problem with the heater control system.

44
Q

What damage would require the cockpit window to be changed ?

A

Cracks or chips in the inner glass pane
Cracks in the outer glass pane
Cracks in the vinyl ply
Scratches more than0.002 inch in depth.

45
Q

What damage can result in the passenger window to be replaced ?

A

Crazing
Cracking
Scratches
Chips
( if extent exceeds the manufactures limit, you must replace )

46
Q

Whats the three designs for the construction of an aircraft’s wing ?

A

Mono-spar = only has one longitudinal member
Multi-spar = has more than one longitudinal member
Box beam = two main longitudinal member.

47
Q

2
FWD, AFT

48
Q

How is a reciprocating engine mounted to the fuselage ?

A

Engine mount structure made from steel.
( v-struts )

49
Q

Does the top or bottom bolts of the engine mount, support a reciprocating engine while on the ground ?

A

Top
( when aircraft is airborne, a torsional stress is added and effects all bolts )

Q

Whats the section called where the engine is attached ?

A

Engine mount ring

51
Q

How is the engine attached to the mount ?

A

Dynafocal mounts
( reduces the vibration passed from engine to the fuselage )
