A heavy circumferential structure that may or may not be entirely closed by a web is known as a
Frame
Brace
Ring
Bulkhead
Which aircraft structure is being replaced in this picture?
Rib
Longeron
Spar
Intercostal
A principal longitudinal member of the framing of an aircraft fuselage or nacelle which is usually continuous across a number of points is known as a
(a)
Why would NDI be called back a second time after damage has been removed?
To get paid.
To ensure no cracks or disbonding occurred during the final cutout.
To confirm alodine was applied properly.
To make sure there is a half inch radius in the corners of any cutout.
What should you keep in mind while building made repair parts?
Temper.
Grain direction.
Gauge.
Specifications.
A metal part, other than a flat sheet, which is formed or extruded and used in the framing of a structure to provide rigidity.
(a)
Monocoque is
a single shell construction in which the skin carries the stress.
structure consisting of multiple parts working together to transmit stresses.
an absurd french word.
a strong member that forms the edges of beam structures or heavy frames.
Symmetry checks are
optional, and only take place if an aircraft is subjected to severe turbulence.
carried out to ensure that the aircraft is true to the design characteristics of the original configuration.
typically carried out after a major repair is complete to ensure the aircraft has been returned to its original configuration.
carried out using a plumb bob from specific points as called out by the manufacturer.
The purpose of bracing an aircraft is to
support the aircraft structure and not allow it to sag under its own weight.
to mark the location of the damage.
ensure the aircraft measures within the manufacture's specified limits.
render systems inoperable if they may come into contact with a repair technician.
When installing repair parts in a pressurized area it is mandatory to install them
(a)
What should be done with parts removed from an aircraft?
Tagged as to where they belong, and their relation to the repair.
Inspected and replaced, or repaired as required.
Brought to your inspector for a stamp.
Meticulously researched in the Illustrated Parts Catalog.
Before starting a big repair it is good practice to
call your manager on the hangar rotary phone as ask for a raise.
document the area on the shop polaroid camera to assist in reassembly.
send a morse code to your significant other and let them know you're working late.
telegram the pilot and let them know the aircraft will be late.
reference the VHS library of the aircraft's SRM on the shop VCR.
The most important rule when repairing aircraft structure is
leaving as much of the original structure as possible.
ensuring you have a minimum 1/4" radius in the corners.
building repair parts one gauge heavier than the original material.
getting it done as quickly as possible.
A hat section is
super cute, and can be worn to parties.
a cross sectional shape of some stringers used in the fuselage.
a small stabilizing beam and at right angles to larger beams or bulkheads.
an auxiliary structural member shaped to provide a smooth flow of air.
What safety consideration should you have before performing a repair?
Locking out hydraulic and electrical systems.
Marking the area of damage with a grease pencil on the structure involved.
Ensuring there is sufficient lighting.
Ensuring the area in question is free of bats.

When drilling out rivets it's very important to upsize as many holes as possible?
True
False
The main advantage of a semi-monocoque structure
lies in the fact that it does not depend on a few members for strength and rigidity.
is the cost effectiveness of of its construction.
is that its single shell construction carries all the shear and bending stresses.
repairing it can be quite complicated, therefore helping to rack up overtime.
