    1. GENERAL TIE-DOWN AND MOORING

    3. TM 1-1500-250-23 Every installation with Army aviation units will have secure mooring points for all assigned aircraft. Where points are not sufficient, installation engineers will take immediate action to install required mooring points.

    4. TM-1-1500-250-23 NOTE: If unable to conform to the configurations shown within this TM, contact AMCOM Engineering (DSN 693-1679) for guidance. Chains are to be attached to the aircraft as illustrated in the aircraft figure in the TM and are to be adjusted to remove slack in the chains.

    5. TM 1-1500-250-23 Exceptions to the use of mooring chains is only approved under special circumstances where chain has proven to be undesirable such as the crossover mooring on the CH-47D. The CGU-1B, 5000 pound capacity nylon tie-down strap is only authorized when hard stand mooring points are not available and the field mooring kit is used.
