The life of the structure is counted by flying hours landings pressurization cycle. What are buttock lines? Vertical measurement lines Horizontal measurement lines Measurements from the centre line. Aircraft fibreglass panels are protected against lightning strikes, partially by conductive paint non-conductive paint bonding. A member taking a compression load is called a beam strut cable. Stringers are used in which of the following types of aircraft fuselage construction? Semi-monocoque Truss type Monocoque. Wing stations are measured outboard from the wing root inboard from the wing upper surface outboard from the fuselage centreline. What load is a tie rod designed to accept? Bending Tensile Torsion. If a colour is used to identify primary structure, it will be yellow green red. Which of the following is primary structure? Stringer Frame Skin. Fuselage station numbers are measured from the front of the aircraft in inches feet feet and inches. Which parts of the aircraft are classified secondary structures? These parts of the airframe are highly stressed but if damaged will not cause failure of the aircraft These parts of the airframe are highly stressed and if damaged may cause failure of the aircraft and loss of life These are lightly stressed parts such as fairings, wheel shields and minor component brackets etc. Structure with built‑in redundancy is called failsafe double safe safe life. Stress is the load per unit area acting on a material is the deformation of a material caused by applied load is the property of a material to resist fracture. A piece of structure which must be replaced at a specified number of cycles, flying hours or years, regardless of its physical condition is what type of item? Fail-safe Safe-life Condition monitored. Safe-life is the sharing of loads between adjacent members the maximum number of flying hours that should elapse before a major structural failure occurs the minimum number of flying hours that should elapse before a major structural failure occurs. Bending stresses are a combination of tension and compression stresses torsional and compression stresses tension and shear stresses. The Airworthiness Notice that refers to structural surveys is Notice 65 Notice 89 Notice 79. Structural survey inspections are normally called up by the maintenance engineer manufacturer operator. Where are wing stations measured from? Butt Line (BL) Zone Line (ZL) Water Line (WL). Where is Zone 323? Between rear spar and trailing edge Tip of vertical stabiliser Between front and rear spar. To prevent a system being affected by high current flows after a lightning strike to a composite aircraft, electricity is discharged through electrically connected primary conductors a sprayed coat of non-conductive paint a sprayed coat of conductive paint. A structural member intended to resist compression is a strut tie web. An aircraft structure, having multiple load paths, is known as a fail-safe design monocoque design safe-life design. Wrinkling of the skin on the upper surface of the fuselage indicates sagging shedding hogging. If a redundant structure fails it becomes fatigued safe-life failsafe. A redundant structure is on-condition structure a safe-life structure a failsafe structure.

Kevlar should be stored horizontally. in moisture proof bags. vertically. To remove a rivet chisel off the rivet head, and remove the shank with a metal punch. drill the head with a drill bit the same size as the rivet shank, chisel off the rivet head, and remove the shank with a metal punch. drill the head with a drill bit slightly smaller than the rivet shank, chisel off the rivet head, and remove the shank with a metal punch. Battery trays are absorbent to soak up electrolyte. metal with PVC coating and anti corrosive paint. metal for earthing purposes. The primary purpose of sealant in use in pressurised aircraft is to prevent corrosion. to provide external streamlining. to seal the cabin. When installing a 'Hi-lock' bolt, it is necessary to simply fit the bolt as they are prelubricated. lubricate the collar. lubricate the shank and threads. Sealant or levelling compound is installed during structure repair: according to separate manufacturer's documentations such as BAC. according to SB instructions. according to AMM and SRM chapter 51.
