16B. The Logistics POC will contact the local POC when the purification equipment is available. An OLR
team will train unit personnel to operate the purifier. Replacement filters and maintenance of the purifier
will be the responsibility of the owning unit.
Perform the ILCA Jam Test, Phase 1, of TM 55-1520-240-23-6, Task 7-104.1 or
TM 1-1520-252-23-7, Task 7-124 prior to the first flight of each day. Annotate DA Form
2408-13-1 to reflect this inspection requirement. The following precautions will be taken to minimize wear
and tear on the jam buttons and their seals:
Excessive force applied to the jam button may cause damage to the button,
requiting the replacement of the entire actuator assembly.
(1) Clean the jam button with a dean cloth prior to performing the test.
(2) Do not use a steel tool to depress the button. Use hand pressure with a drift made of a softer
material such as aluminum, brass, or wood to depress the button.
g. Commanders and unit instructor pilots will brief all flight crews that the AFCS is not an automatic
pilot and it is imperative that a pilot continuously monitor aircraft attitude while utilizing the functions of
AFCS. In the event the aircraft deviates from the desired attitude the pilot will immediately man the flight
controls and make corrective inputs to correct deviations.
h. All Depots, Field/Support Units, and Contractor Maintenance Facilities will not use alcohol or
chlorinated solvents or cleaners in hydraulic maintenance or to clean parts of the hydraulic system.
All Depots, Field/Support Units, and Contractor Maintenance Facilities will ensure that hydraulic
test stands for H-47 Flight Control and Utility System Components are serviced with MIL-H-83282. This
fluid will be used as a preservative fluid to eliminate traces of barium in hydraulic components. MIL-H-
83282 contains sufficient corrosion protection for component storage.
Number 1 and Number 2 Flight Boost Pressure and Return Fitter Elements will be replaced at
the next phase and every 400 hours thereafter. ULLS-A units will use Inspection Legitimate Code
Number A-380 for the Number 1 and 2 Flight Boost Pressure and Return Filter Replacement due
every 400 hours.
