What is the approximate piston displacement of this engine? 200 cubic inches. 235 cubic inches. 360 cubic inches.
An aircraft Type Certificate Data Sheet contains: location of the datum. control surface adjustment points. maximum fuel grade to be used.
Primary responsibility for compliance with Airworthiness Directives lies with the: certificated mechanic holding an Inspection Authorization who conducts appropriate inspections. certificated mechanic who maintains the aircraft. aircraft owner or operator.
The color of 100LL fuel is: blue. colorless or straw. red.
(Refer to Figure 36 .) The diameter of the holes in the finished object is: 31/64 inch. 1/2 inch. 3/4 inch.
How is the locking feature of the fiber type locknut obtained? By a fiber insert held firmly in place at the base of the load carrying section. By making the threads in the fiber insert slightly smaller than those in the load carrying section. By the use of an unthreaded fiber locking insert.
Which atmospheric conditions will cause the true landing speed of an aircraft to be the greatest? Low temperature with low humidity. High temperature with high humidity. High temperature with low humidity.
How is a flooded engine, equipped with a float type carburetor, cleared of excessive fuel? Crank the engine with the starter or by hand, with the mixture control in cutoff, ignition switch on, and the throttle fully open, until the excess fuel has cleared or until the engine starts. Crank the engine with the starter or by hand, with the mixture control in cutoff, ignition switch off, and the throttle fully open, until the fuel charge has been cleared. Turn off the fuel and the ignition. Discontinue the starting attempt until the excess fuel has cleared.
What does the Type Certificate Data Sheet designation code "2 PCSM" mean? Two place (number of seats), closed, sea, monoplane. Two wing (biplane), primary category, semimonocoque (airframe). Neither of the other two choices.
If each cell, connected in series, equals 2 volts, how would a 12-cell lead acid battery be rated? 24 12 6.
Which of the following includes all the regulatory definitions of "maintenance"? Overhaul, repair, parts replacement, and preservation, and preventive maintenance. Overhaul, repair, parts replacement, preservation, inspection, and preventive maintenance. Overhaul, repair, parts replacement, inspection, and preservation.
If all, or a significant part of a stall strip is missing on an airplane wing, a likely result will be: asymmetrical lateral control at or near stall angles of attack. decreased lift in the area of installation at high angles of attack. asymmetrical lateral control at low angles of attack.
The testing medium that is generally used in magnetic particle inspection utilizes a ferromagnetic material that has: high permeability and low retentivity. low permeability and high retentivity. high permeability and high retentivity.
A fuel that does not vaporize readily enough can cause: detonation. hard starting. vapor lock.
When flaring aluminum tubing for use with AN fittings, the flare angle must be: 39°. 45°. 37°.
(Refer to Figure 47 .) What is the measurement reading on the vernier caliper scale? 1.700 inches. 1.411 inches. 1.436 inches.
A nonelectrolytic chemical treatment for aluminum alloys to increase corrosion resistance and paint bonding qualities is called: alodizing. anodizing. dichromating.
Specifications pertaining to an aircraft model manufactured under a type certificate, of which less than 50 are shown on the FAA Aircraft Registry, can be found in the: Aircraft Listing. Summary of Discontinued Aircraft Specifications. FAA Statistical Handbook of Civil Aircraft Specifications.
If the reference datum line is placed at the nose of an airplane rather than at the firewall or some other location aft of the nose, all measurement arms will be in negative numbers. measurement arms can be either positive or negative numbers depending on the manufacturer's preference. all measurement arms will be in positive numbers.
Which statement is applicable when using a sketch for making a part? The sketch must show all information to manufacture the part. The sketch may be used only if supplemented with three view orthographic projection drawings. The sketch need not show all necessary construction details.
Of the following, when and/or where is galvanic corrosion is most likely to occur? When an electrolyte (water) covers the surface of an aluminum skin, seeps into the cracks between lap joints, and oxygen is excluded from the area. At the interface of a steel fastener and aluminum alloy inspection plate in the presence of an electrolyte. In an area of unprotected metal exposed to an atmosphere containing battery fumes, exhaust gases, or industrial contaminants.
When computing weight and balance, an airplane is considered to be in balance when: all moment arms of the plane fall within CG range. the movement of the passengers will not cause the moment arms to fall outside the CG range. the average moment arm of the loaded airplane falls within its CG range.
What is generally used in the construction of aircraft engine firewalls? Chrome molybdenum alloy steel. Stainless steel. Titanium nickel alloy.
Which is correct concerning a parallel circuit? Total resistance will be smaller than the smallest resistor. Total voltage drop is the same as the total resistance. Total resistance will decrease when one of the resistances is removed.
Improper loading of a helicopter which results in exceeding either the fore or aft CG limits is hazardous due to the: coriolis effect being translated to the fuselage reduction or loss of effective cyclic pitch control reduction or loss of effective collective pitch control.
If dye penetrant inspection indications are not sharp and clear, the most probable cause is that the part: was not correctly degaussed before the developer was applied was not thoroughly washed before developer was applied has no appreciable damage.
