CH-47: Need Chinook Covers?

Mechanics,

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.

Fig #	Item	NSN 1730-	PN
1	Engine exhaust cover	01-593-9707	CH-47-202
2	Forward rotor head cover	01-593-9690	CH-47-063
3	FWS XMSN oil inlet cover	01-593-9716	CH-47-068
	Aft rotor hub cover	01-593-9723	CH-47-064
4	Hyd/oil cooler exhaust vent cover set	01-593-9684	CH-47-067
5	APU tail cone exhaust cover	01-593-9515	CH-47-150
6	Center console set cover	01-593-9662	CH-47-127
7	Air inlet and oil cooler exhaust cover	01-593-9697	CH-47-124
8	Cockpit enclosure (windshield and nose)	01-593-9636	CH-47-128
9	Aircraft engine right-hand cover	01-593-9359	CH-47-060
10	Aircraft engine left-hand cover	01-593-9488	CH-47-059

Note: 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.

Item	NSN
Pitot tube cover	1730-01-645-1206
T-714 engine maintenance cover	1730-01-646-0357
CMWS flare dispenser cover left side	5999-01-628-3494
CMWS flare dispenser cover right side	5999-01-628-3466
ATIRCM	5999-01-628-3447
CMWS dual chaff dispenser cover (2 covers)	5999-01-628-3461

Note: 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:

mark.bechtel@envelopcovers.com

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.
