104.1 State the purpose of a hydraulic patch test.
|
The contamination analysis procedures allow determination of the particulate level of a hydraulic system and the presence of .free water or other foreign substances, metallic and non-metallic.
|
|
|
104.2 State the purpose of Blade Inspection Method (BIM) indicator.
|
The purpose of a Blade Inspection Method (BIM) indicator is to indicate when blade pressure is below minimum service pressure.
A color change indicates main rotor blade serviceability. Three black stripes indicates pressure is below minimum service pressure. |
|
|
104.3 State the purpose of conducting Flight Control system rigging.
|
To ensure stick and pedal motion in cockpit are coordinated with correct blade angle at main and tail rotor.
|
|
|
104.4 State the purpose of tactical paint scheme.
|
Tactical paint scheme is designed for each Aircraft type to reduce visual detection by matching the reflectance of operational surrounding. These schemes are composed of flat gray color or with contrasting shades of gray.
|
|
|
104.5 State the two methods of locking/unlocking tail wheel lock-pin.
|
The tail wheel can be manually unlocked by moving the moving the manual override lever of the tail landing gear to the down position. The tail wheel cannot be manually locked.
The tail wheel lock-pin can be electrically locked or unlocked using the tail wheel lock/unlock switch on the lower control panel (only when manual override lever is in the up position). |
|
|
104.6 State the factors that affect helicopter flight.
|
Density altitude, heat, humidity, gross weight, rotor speed, forward airspeed, and altitude.
|
|
|
104.7 State the factors that affect rotor blade lift.
|
Density altitude, rotor speed and angle of attack of rotor blade.
|
|
|
104.8 State the location and purpose of the main rotor head dampers.
|
The main rotor head dampers are installed to restrain hunting (lead/lag) of the main rotor blade. The hunting occurs during rotor engagement and as blades flap in flight. The main rotor head dampers also positions blades full forward for main rotor blade folding.
|
|
|
104.9 Explain how the following flight control affect helicopter flight.
|
a. Collective stick: Used to simultaneously change the pitch of all four blades, increasing or decreasing lift.
b. Cyclic stick: Controls forward, aft, and lateral movements of the helicopter. c. Rudder pedals: Controls helicopter heading. |
|
|
104.10 State what must be done for effective helicopter corrosion prevention.
|
Complete flushing of the aircraft surface with clean fresh water shall be done daily after the last flight followed by a general wipe down and lubrication/preservation.
|
|
|
104.11 State the two areas of the helicopter which must have particular attention during a corrosion inspection.
|
Pay particular attention to the underside of the helicopter structure and transmission where moisture tends to collect. (A1H60CA-SRM-300, WP 005, PG. 3, Para 4. d.)
|
|
|
104.12 State the approved cleaning materials and methods.
|
MIL-C-85570, type II aircraft cleaning compound is the only alkaline cleaner authorized for use on H-60 aircraft.
Normal washing: Mix one part cleaning compound to four parts water. Light duty washing: Mix one part cleaning compound to nine parts water. Heavy duty washing: Mix one part cleaning compound to one parts water. NOTE: For in-depth details, see A1-H60CA-GAI-010. |
|
|
104.13 State the purpose for emergency reclamation procedures
|
Emergency reclamation procedures is normally used to prevent further damage and will usually require further treatment at a higher level of maintenance. Emergency reclamation procedures are used when the aircraft is exposed to gross amounts of salt water or fire extinguishing agents.
