Production Planning

Planning System organisation shall have a system appropriate to the amount and complexity of  work to plan the availability of all necessary personnel, tools, equipment, material, m data and facilities in order to ensure the safe completion of the maintenance work. Planning of maintenance tasks , and the organising of shifts, shall take into account human performance limitations. Hand over - When it is required to hand over the continuation or completion of maintenance tasks  for reasons of a shift or personnel changeover, relevant information shall be adequately communicated between outgoing and incoming personnel. The absence of effective planning can contribute towards increased work pressure. Work pressure itself may lead to deviation from procedures. Deviation from procedures is well known as a contributing factor in many aircraft incidents. The AMO should give due importance and clarify the objective of good planning. Advisory and explanatory material should i...

Cessna 172R Shimmy Damper

NOSE LANDING GEAR SHIMMY DAMPER – SERVICING PROCEDURE A. Service the shimmy damper every 100 hours. B. Service the shimmy damper as follows: (1) Remove the shimmy damper from the airplane. (2) While you hold the damper in a vertical position with the fitting end pointed down, pull the fitting end of the damper shaft to its limit of travel. (3) While you hold the damper in this position, fill the damper through the open end of the cylinder with hydraulic fluid. (4) Push the shaft up slowly to seal off the filler hole. (5) Clean the damper with solvent. Make sure that the shaft comes out through the filler hole until the damper is installed on the aircraft. (6) Install the damper on the airplane. C. Keep the shimmy damper clean. (1) Clean the shimmy damper with a clean, lint-free cloth to prevent the collection of dust and grit. (2) Make sure that the part of the damper piston shaft that you can see is always clean. (3) Clean the machined surfaces of the shimmy damper. (a) ...

Cessna 172R ELT Remote Switch & buzzer

Image
           Remote Switch : The Artex standard remote switch is designed so that if its wires are cut or shorted together the emergency operation of the ELT is unhampered although the ELT may activate and not “reset” if the wires are shorted together.              Select a switch mounting location that is easily seen and reached by the pilot and out of direct sunlight. The Artex remote switch requires approximately 1.3” X 2.0” (33 X 50.8 mm) of panel area to mount. A space is also required for a warning placard, measuring 2.25” X 0.25” (57 X 6.5 mm), which should be placed close to the installed switch. Approximately 3 inches (75mm) of clearance behind the panel is required for the switch assembly, mating connector and harness. Mark and remove the rectangular cutout for the remote switch assembly. Dimensions are shown in the Specifications. Fit the switch assembly into the cutout and mark the four mounting screw h...

Cessna 172R ELT Antenna

Image
The ELT antenna must be mounted in accordance with the requirements. Locate the antenna at least 30 inches (75 cm) away from other antennas, wires, vertical stabilizer, etc. to minimize distortion of the radiated field and interference with other equipment. The antenna must be installed VERTICALLY (within ±15ยบ of the vertical plane is acceptable). Artex has no performance data for installations that deviate from the stated requirements. The ME406 is certified to be used with the following antennas (automatic fixed “AF” configuration): • Artex Whip Antenna, 121.5/406 MHz, P/N 110-773 • Artex Rod Antenna, 121.5/406 MHz, P/N 110-338 The antenna requires a ground plane. On aircraft constructed with non-conductive materials, such as composite materials or fiberglass, a ground plane must be added. Ideally, the ground plane should extend out from the antenna mounting point at least 24 inches (60cm) in every direction. Many times this is not possible, but an effective plane can be constr...
