Your Chinooks come with primary covers for different parts of the aircraft. You’ll find these covers listed in the TMs.
Chinook Primary Covers
Here’s a list of the primary covers for the Chinook. Keep this info as a handy reference.
||Engine exhaust cover
||Forward rotor head cover
||FWS XMSN oil inlet cover
||Aft rotor hub cover
||Hyd/oil cooler exhaust vent cover set
||APU tail cone exhaust cover
||Center console set cover
||Air inlet and oil cooler exhaust cover
||Cockpit enclosure (windshield and nose)
||Aircraft engine right-hand cover
||Aircraft engine left-hand cover
: Items 9 and 10 both depict covers designed for two configurations, one with and one without the external air particle separator (EAPS) and infra-red suppression system (IRSS) installed. This system lowers the heat signature of engine exhaust.
Cocoon, Inc., the manufacturer of these covers, will also provide hands-on training if requested. The POC is Jim Crotty at:
Chinook Alternate Covers
Just in case you don’t have the primary covers on hand, the Chinook PM has provided seven (7) approved alternate covers
for your aircraft.
|Pitot tube cover
|T-714 engine maintenance cover
|CMWS flare dispenser cover left side
|CMWS flare dispenser cover right side
|CMWS dual chaff dispenser cover (2 covers)
The alternate cover NSNs are coded Y (terminal) in the supply system. That’s because DLA stops ordering them when they don’t receive requisitions over time. The Chinook PM office has requested re-establishment of the NSNs, but this will take some time. In the meantime, units need to order the covers to build demand. Then DLA will restock the covers. So if you need the covers, start ordering them now
These covers come from a third party source and the NSNs won’t be added to the TMs, so make a note.
If you order the covers, you have the option of a free, three-part, on-site training session from the manufacturer. The training allows Soldiers to prevent damage to aircraft, components and equipment, while extending the life of the covers. To arrange for the training, contact Shield Technologies Corporation at (715) 441-0280, or email:
The three-part training includes:
- information about the unique anti-corrosion cover technology and how it benefits your aircraft and equipment.
- hands-on training to properly install, remove and care for the covers.
- a CD with written instructions on how to properly install, remove and care for the covers. The CD also helps train new Soldiers and provides refresher training.
