Q-2R (Tape and pin inspection/ "long pulls") |
pull tape out, pull pin, clean, and inspect pin for cuts/abrasions, bends/dents, corrosion, or other damage. Re-coat pin a with aircraft grease, inserted properly through sewn-loop, and seated correctly, with stitches facing inboard. Pull tractor to check security of tape and pin for proper seating. |
|
|
R-2 |
Post arrestment inspection, inspect tape for wear spots, proper width, and any cuts/abrasions. |
|
|
(R-2) Any frays must be cut off and ____ applied to tape. |
Gaco |
|
|
Must be above ____ to apply Gaco or Grikote |
40°f |
|
|
R-3 |
CDP inspection. Inspect CDP for bird-caging, necking down, and broken wires. Inspect wire supports(donuts) for deep cuts/tears, maintaining proper height of CDP, flat spots, and cracks. |
|
|
(R-3) Apply ____ as needed to prevent degradation of CDP. |
Grikote |
|
|
Must keep a minimum of ___ wire supports(donuts) on CDP at all times, maximum of ___ |
8, 12 |
|
|
M-1R : Inspection and lubrication of arresting gear (Short Pulls). Ensure preliminary tasks accomplished prior to starting maintenance check. Preliminary include: greasing all zero fittings on sheaves, sprockets, clutch, ujoint, and rollers underneath drum; all fluid levels checked and hazmat added as necessary, including ATF in dual cam clutch and TSP, 80W-90 oil in speed reducer, 10W-30 oil in engine. Clutch must be engaged to check ATF level in TSP. |
Proper dyno readings of breaking strength (6000-6500 ft lb, 3 consecutive pulls) correct torque of locking screws (67 ft lb) QA will inspect readings and proper functions of rollers. |
|
|
A-1 |
Sheave inspection: clean sheaves of all grease, inspect for cuts/abrasions, and re-grease sheave. Inspect roller bearing for proper function. All o-rings and locking nuts must be replaced. |
|
|
S-1R |
Spark plug and limit switch inspection: replace spark plugs, ensuring proper torque to prevent breakage of plugs (22 ft lbs) and proper gapping of plugs (0.030 inches) apply water-displacing compound to limit switch, allowing to dry completely before reconnection. |
|
|
S-2R |
Antifreeze strainer and salinity test: ensure strainer is free of debris. Check for proper Antifreeze fluid level (10" + 1/2"). Test Antifreeze freezing point using refractometer (between -45°f to -65°f). Test proper pH level using litmus paper (7.0 pH) |
|
|
S-3R |
Oil change: Drain oil, replace oil filter and oil. Each engine takes average of 7 quarts of 10W-30. Add 6 quarts of oil, run for approximately 5 mins, then add additional oil as necessary. Oil filter must be lubricated and dated before installation. |
