refer to figure 46. the measurement reading on the illustrated micrometer is. 0.2851. 0.2911. 0.2901.

refer to figure 48. what does the micrometer read?. .2974. .3004. .3108.

what precision measurement tool is used for measuring crackpin and main bearing journals for out of round wear?. dial gauge. micrometer caliper. depth gauge.

refer to figure 47. what is the measurement reading on the vernier caliper scale?. 1.411 inches. 1.436 inches. 1.700 inches.

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.

who has the authority to approve for return to service a propeller after 100 hour inspection? 1. a mechanic with a powerplant rating 2. any certificated repairman 3. a non-certificated mechanic working under the supervision of a certificated mechanic with aiframe and powerplant ratings. 1. 2. 1 and 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 aicraft 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.

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. 2 and 3. 2. 1.

if it is necessary to accurately measure the diameter of a hole approximately 1/4 inch in diameter, the mechanic should use a. telescoping gauge and determine the size of the hole by taking a micrometer reading of the adjustable end of the telescopic gauge. 0 to 1 inch inside micrometer and read the measurement directly from the micrometer. small-hole gauge and determine the size of the hole by taking a micrometer reading of the ball end of the gauge.

which number represent the vernier scale graduation of a micrometer. .00001. .001. .0001.

what tool is generally used to calibrate a micrometer or check its accuracy?. gauge block. dial indicator. machinist scale.

which tool is used to measure the clearance between a surface plate and relatively narrow surface being checked for flatness?. depth gauge. thickness gauge. dial indicator.

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 1 is true. only 2 is true. both 1 and 2 are true.

refer to figure 49 the measurement reading on the micrometer is. .2758. .2702. .2792.

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

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.

during an annual inspection, if a defect is found which makes the aircraft unairwhorthy, the person disapproving must. void the aicraft aiworthiness certificate. submit a malfunction or defect report. provide a written notice of the defect to the owner.

identify the correct statement. an outside micrometer is limited to measuring diameters. tools used on certificated aicraft must be an approved type. dividers do not provide a reading when used as measuring device.

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

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 used to separate metals or alloys and their heat treated conditions?. eddy current inspection. ultrasonic inspection. magnetic particle inspection.
