Chinook Alternate Covers Approved

Mechanics, your Chinooks come with primary covers for different parts of the aircraft. You’ll find these covers listed in the TMs.

In case you don’t have the primary covers on hand, the Chinook headshed has provided three approved alternate covers for the pitot tube, the T-714 engine, and the rotor head:

Item NSN 1730-
Pitot tube cover 01-645-1206
T-714 engine maintenance cover 01-646-0357
Rotor head maintenance cover 01-646-0358


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. To arrange for the training, contact:

Mark Bechtel

Shield Technologies Corporation


The three part training covers:

  • 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.

The training prevents damage to aircraft, components and equipment, while extending the life of the covers.         Primary Cover NSNs
