After obtaining proof of receipt from supply, the transferring activity attaches a copy of DD Form 1149 to the AIR. The transferring activity retains one receipt copy of DD Form 1149 as their record. When a ferry pilot is required to effect an aircraft transfer, it requires two inventories. One inventory by the transferring activity prior to the ferry pilot and another by the accepting activity. The ferry pilot does not participate in the inventory of aircraft. However, the ferry pilot accepts custody of pilferable and classified equipment from the transferring activity. The ferry pilot transfers the custody of these items to the accepting activity. AIR items not transported on the aircraft are shipped separately. These items must be marked “AIR Equipment for Aircraft BUNO.” Note this shipment in column E of AIR Equipment List opposite each affected equipment. AIR items not required for mission accomplishment may be removed from the aircraft and lined out of the applicable AIR Equipment List. Before doing this, the activity must have approval from the applicable ACC/TYCOM and NAVAIR. When approved, the activity can process the items for turn-in to supply. The activity enters the name of the removing organization and turn-in control number in column E of OPNAV 4790/111. In addition, the organization records the appropriate entry in OPNAV 4790/112. In this situation, NAVAIR continues to maintain required quantity of items on MAIR. NAVAIR does this because the same type of aircraft in other commands requires continued usage of the equipment. TRANSFER ON SITE.— When transferring aircraft on site, the transferring and accepting activity jointly inventory the aircraft. The inventory team records the quantity of each item on the aircraft at the time of transfer. The team uses the AIR Equipment List (OPNAV 4790/111) to record these items. Also, the team completes the AIR Shortages (OPNAV 4790/112) to identify shortages of AIR and MESM items that are not available for transfer. A Certification and Record of Transfer (OPNAV 4790/104) must be completed at the time of transfer. D E L I V E R Y  T O  D E P O T  O R  C O N- TRATOR.— An aircraft maybe delivered to a depot or contractor facility and scheduled for return to the originating organization, In this case, the originating organization retains those items not required for rework, testing, or special projects. The originating activity should note those removed items on the OPNAV 4790/112. This will relieve the accepting depot or contractor of accountability requirements. The OPNAV 4790/104 must be certified during the transfer action. TRANSFER VIA DEPOT OR CON- TRACTOR.— When transferring aircraft via depot or contractor, the transferring activity ships only the minimum of essential AIR items. The transferring activity notes shortages on OPNAV 4790/112. The remaining equipment must be shipped to the receiving activity 30 days prior to the scheduled depot or contractor completion date. The OPNAV 4790/104 must be certified during this transfer action. Shortages Prior to transfer, list all missing AIR and MESM-related items on OPNAV 4790/112. The transferring activity retains the original copy of OPNAV 4790/112 as a permanent record of transfer. A second copy remains in the AIR and is delivered to the accepting activity. Forward a third copy to the ACC/TYCOM of the transferring activity. In the case of transfer between ACC/TYCOM, forward the third copy of the form to the ACC/TYCOM of the accepting activity. A fourth copy will be forwarded to one of the appropriate commands listed  in the following texts, Commander, Fleet Air (COMFAIR) Commanding General, Marine Aircraft Wing (CGMAW) Functional Wing Commanding General, Marine Brigade (CGMARBDE) To relate AIR shortages to any specific inventory or transactions, enter the following information on OPNAV 4790/112. . Name of transferring/receiving activity l Equipment check/certification number c Date l Signature of inventorying activity’s CO or representative authorized to sign by direction You must make every effort to find the items revealed as missing during inventory. However, transfer of aircraft will not be delayed pending replacement of the items. In this case, the transferring activity makes entries to OPN4V 4790/112. If a missing item was removed for repair, enter a notation in column D of OPNAV 4790/112. Take the necessary steps to ensure the items are forwarded and marked for the proper 8-18
