INTRODUCTION This Work Package (WP) covers the rigging of a non-flyable OH-58A/C with a damaged tail-boom using a one-hook long-line recovery procedure, the rigging of a CH-47 or UH-60 recovery helicopter, the recovery flight, and post recovery procedures. The long-line one-hook procedure provides for 90 feet of clearance between the recovery helicopter’s single cargo hook in use and the shackle assembly that the damaged helicopter is rigged to. Damaged Tail-Boom classification consists of a tail-boom that is cracked and/or broken and not suitable as a lift point. The ground rigging crew with the Unit Maintenance Aerial Recovery Kit (UMARK) can be deployed separately or with the recovery helicopter. The recovery process includes rigging the damaged helicopter, rigging the recovery helicopter, hooking up the recovery helicopter to the damaged helicopter, and having the recovery helicopter transport the damaged helicopter to a designated site. Refer to Work Package 0001 00 for general information concerning the UMARK function and component details. 2. PRE-RECOVERY PROCEDURES WARNINGTo prevent catastrophic failure do not use the UMARK if its record log indicates 20 or more aerial recovery uses. Ensure that a pre-usage inspection is performed on the UMARK contents as outlined in Work Package 0027 00. Do not use the UMARK kit if the kits usage log indicates 20 or more uses of the kit. Refer to Work Package 0027 00 for disposition instructions if the kit has 20 or more uses. Do not use the kit if any required content items fail pre-usage inspection. 0015 00-1
