| When dealing with weight and balance of an aircraft, the maximum weight is interpreted to mean the maximum | authorized weight of the aircraft and its contents. |
| Which of the following have an effect on aircraft CG results when conducting a weight and balance check? | Leaving the downlocks installed. there should be no equipment installed that is not included in the equipment list. |
| (1) Private aircraft are required by regulations to be weighed periodically. (2) Private aircraft are required to be weighed after making any alteration. Regarding the above statements, | neither 1 nor 2 is true. No Federal Aviation Regulation requires that private aircraft be weighed periodically. After making alterations the weight and balance is normally found mathematically rather than by actually weighing the aircraft. |

| Improper loading of a helicopter which results in exceeding either the fore or aft CG limits is hazardous due to the | reduction or loss of effective cyclic pitch control. |
| The maximum weight as used in weight and balance control of a given aircraft can normally be found | in the Aircraft Specification or Type Certificate Data Sheet. |
| the total empty weight of an aircraft is 5,862 pounds with a moment of 885,957. the aircraft was weighed, 20 pounds of potable water were on board at +84, and 23 pounds of hydraulic fluid were in a tank located at +101. What is the EW CG of the aircraft? | 151.365 |
| What should be clearly indicated on the aircraft weighing form? | the weighing form used with a specific aircraft should specify not only the leveling means, but also the location of the weighing points. |
| The useful load of an aircraft consists of the | crew, usable fuel, passengers, and cargo. |
| When, or under what condition(s) are adverse loading checks conducted? | nytime a repair or alteration causes EWCG to fall outside the CG range. |
| The maximum weight of an aircraft is the | empty weight plus useful load. |
| Which should be accomplished before jacking an aircraft? | Install critical stress panels or plates. |
| When computing the maximum forward loaded CG of an aircraft, minimum weights, arms, and moments should be used for items of useful load that are located aft of the | forward CG limit. |

| When flaring aluminum tubing for use with AN fittings, the flare angle must be | 37° |
| The maximum distance between end fittings to which a straight hose assembly is to be connected is 50 inches. The minimum hose length to make such a connection should be | the hose should be at least 5 percent longer than this, or 52-1/2 inches long. |

| Which statement is true regarding flattening of tubing in bends? | the bend is not satisfactory if its small diameter is less than 75 percent of the outside diameter of the straight tubing. |
| In most aircraft hydraulic systems, two-piece tube connectors consisting of a sleeve and a nut are used when a tubing flare is required. The use of this type connector eliminates | the possibility of reducing the flare thickness by wiping or ironing during the tightening process. |
| What is the color of an AN steel flared-tube fitting? | Black |
| Which of the following hose materials are compatible with phosphate-ester base hydraulic fluids? | Butyl and Teflon. |
| The material specifications for a certain aircraft require that a replacement oil line be fabricated from 3/4-inch 0.072 5052-0 aluminum alloy tubing. What is the inside dimension of this tubing? | Find the inside diameter of a tube by subtracting two times the wall thickness from its outside diameter. 0.750 - 2(0.072) = 0.606 inch The inside diameter is 0.606 inch. |
| Flexible hose used in aircraft systems is classified in size according to the | inside diameter. |
| Hydraulic tubing, which is damaged in a localized area to such an extent that repair is necessary, may be repaired | by cutting out the damaged area and utilizing a swaged tube fitting to join the tube ends. |
