14 CFR Part 43.
What type of measurement is used to designate the arm in weight and balance computation?
Distance
What is the normal duration of a mechanic certificate with airframe and/or powerplant ratings?
Until surrendered, suspended, or revoked.
The boiling point of a given liquid varies
directly with pressure.
Unless otherwise specified, any values given for current or voltage in an ac circuit are assumed to be
effective values
Working drawings may be divided into three classes. What are they?
Detail drawings
assembly drawings
installation drawings
When an aircraft is sold, the Airworthiness Certificate
is transferred with the aircraft at the time of sale.
Why is it generally necessary to jack an aircraft indoors for weighing?
So that air currents do not destabilize the scales.
To allow for a review of his/her application and supplementary documents
If the temperature of a confined liquid is held constant and its pressure is tripled, the volume will
remain the same.
The method used to rapidly charge a nickel cadmium battery utilizes
constant voltage and varying current
What type of drawing is a description of an object made up of two or more parts
assembly drawing
Where is the record of compliance with Airworthiness Directives or manufacturers' service bulletins normally indicated?
Aircraft maintenance records.
Where do you look to determine the operating c.g. range when calculating a new aircraft weight and balance document?
It is found in the type certificate data sheet.
14 CFR part 65 subpart D contains information for the certification of
mechanics
The speed of sound in the atmosphere changes how?
A fully charged lead-acid battery will not freeze until extremely low temperatures are reached because
most of the acid is in the solution
The measurements showing the ideal or "perfect" sizes of parts on drawings are called
dimensions
During an annual inspection. if a defect is found which makes the aircraft unairworthy, the person disapproving must
provide a written notice of the defect to the owner.
What should be clearly indicated on the aircraft weighing form?
Weighing points
What is the maximum penalty for cheating or other unauthorized conduct when taking an FAA mechanic test?
Ineligibility to receive any certificate or rating for one year, and suspension or revocation of any certificate held.
The speed of sound in the atmosphere is most affected by variations in which of the following?
Ambient temperature
The generation of a voltage in an electric circuit by a changing current in the same circuit is called...
self-inductance
A specific measured distance from the datum or some other point identified by the manufacturer, to a point in or on the aircraft is called a
station number
An aircraft was not approved for return to service after an annual inspection and the owner wanted to fly the aircraft to another maintenance base. What must the owner obtain prior to flight?
The owner must obtain a special flight permit.
When dealing with weight and balance of an aircraft, the term "maximum weight" is interpreted to mean the maximum...
authorized weight of the aircraft and its contents.
What is the maximum duration of a temporary mechanic certificate?
If the volume of a confined gas is doubled (without the addition of more gas), the pressure will (assume the temperature remains constant)
be reduced to one half its original value.
The purpose of providing a space underneath the plates in a lead acid battery's cell container is to
prevent sediment buildup from contacting the plates and causing a short circuit.
For sketching purposes, almost all objects are composed of one or some combination of six basic shapes; these include the
1. Triangle
2. Circle
3. Cube
4. Cylinder
5. Cone
6. Sphere
After making a certain repair to an aircraft engine that is to be returned to service, an FAA Form 337 is prepared. How many copies are required and what is the disposition of the completed forms?
Two; one copy for the aircraft owner and one copy for the FAA
What determines whether the value of a moment is preceded by a plus or a minus sign in aircraft weight and balance?
The result of weight being added or removed and its location relative to the datum.
Who may perform and return to service minor repairs to a propeller?
Any certified mechanic with a powerplant rating.
If two actuating cylinders which have the same cross sectional area but different lengths of stroke are connected to the same source of hydraulic pressure, they will exert....
equal amounts of force and will move at the same rate of speed.
