The side clearances of piston rings are measured with a. micrometer caliper gauge. thickness gauge. dial gauge.

How can the dimensional inspection of a bearing in a rocker arm be accomplished?. Depth gauge and micrometer. Thickness gauge and push-fit arbor. Telescopic gauge and micrometer.

The twist of a connecting rod is checked by installing push-fit arbors in both ends, supported by parallel steel bars on a surface plate. Measurements are taken between the arbor and the parallel bar with a. dial gauge. height gauge. thickness gauge.

Which tool can be used to determine piston pinout-of-round wear?. Telescopic gauge. Micrometer caliper. Dial indicator.

What tool is generally used to calibrate a micrometer or check its accuracy?. Gauge block. Dial indicator. Machinist scale.

Which of these nondestructive testing methods is suitable for the inspection of most metals, plastics, and ceramics for surface and subsurface defects?. Eddy current inspection. Magnetic particle inspection. Ultrasonic inspection.

What nondestructive testing method requires little or no part preparation, is used to detect surface or near surface defects in most metals, and may also be used to separate metals or alloys and their heat treat conditions?. Eddy current inspection. Ultrasonic inspection. Magnetic particle inspection.

A mechanic has completed a bonded honeycomb repair using the potted compound repair technique. What nondestructive testing method is used to determine the soundness of the repair after the repair has cured?. Eddy current test. Metallic ring test. Ultrasonic test.

1. In nondestructive testing, a discontinuity may be defined as an interruption in the normal physical structure or configuration of a part. 2. A discontinuity may or may not affect the usefulness of a part. Regarding the above statements,. only No. 1 is true. only No. 2 is true. both No. 1 and No. 2 are true.

During an annual inspection, if a defect is found which makes the aircraft unairworthy, the person disapproving must. void the aircraft's Airworthiness Certificate. submit a Malfunction or Defect Report. provide a written notice of the defect to the owner.

When a 100-hour inspection is completed, if separate maintenance records for the airframe, powerplant(s), and propeller(s) are maintained, where is the entry for each recorded?. In each record. In the airframe record only. In any one of the records.

Who is responsible for making the entry in the maintenance records after an annual, 100-hour, or progressive inspection?. The owner or operator of the aircraft. The person approving or disapproving for return to service. The designee or inspector representing the FAA Administrator.

An aircraft owner was provided a list of discrepancies on an aircraft that was not approved for return to service after an annual inspection. Which of the following statements is/are true concerning who may correct the discrepancies? 1. Only a mechanic with an inspection authorization. 2. An appropriately rated mechanic. 3. Any certificated repair station. 1. 2. 2 & 3.

What is/are the appropriate action(s) concerning minor repairs performed on a certificated aircraft? 1. FAA Form 337's must be completed. 2. Entries must be made in the aircraft's maintenance record. 3. The owner of the aircraft must submit a record of all minor repairs to the FAA at least annually. 2. 2 and 3. 1 and 2.

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. Which statement is correct?. The owner must obtain a special flight permit. The owner may fly without restriction up to 10 hours. The owner may fly in the restricted category up to 10 hours.

Each person performing an annual or 100-hour inspection shall use a checklist that contains at least those items in the appendix of. 14 CFR Part 43. 14 CFR Part 65. AC 43.13-3.

After a mechanic holding an airframe and powerplant rating completes a 100-hour inspection, what action is required before the aircraft is returned to service?. Make the proper entries in the aircraft's maintenance record. An operational check of all systems. A mechanic with an inspection authorization must approve the inspection.

Which of the following may a certificated airframe and powerplant mechanic perform on aircraft and approve for return to service? 1. a 100-hour inspection. 2. an annual inspection, under specified circumstances. 3. a progressive inspection, under specified circumstances. 1, 3. 1, 2. 1, 2, 3.

The 100-hour inspection required by Federal Aviation Regulations for certain aircraft being operated for hire may be performed by. persons working under the supervision of an appropriately rated mechanic, but the aircraft must be approved by the mechanic for return to service. appropriately rated mechanics only if they have an inspection authorization. appropriately rated mechanics and approved by them for return to service.

Who has the authority to approve a propeller for return to service after a 100-hour inspection?. A certificated mechanic with a powerplant rating. Any certificated repairman. A non-certificated mechanic working under the supervision of a certificated mechanic with airframe and powerplant ratings.
