Narrative:

Aircraft l-hand pack ram air system inoperative. Removed and replaced l-hand pack ram air inlet door actuator per maintenance manual. Opened air-conditioning bay door to inspect system and check ram air system cable tension. Performed operations check of ram air system. System operations check good. Closed and secured all air- conditioning bay doors. Aircraft departed ZZZ safely and on time. Callback conversation with reporter revealed the following information: mechanic was contacted and made the following statement. I replaced the left pack inlet door actuator per the maintenance manual. I performed the operational checks of the left air-conditioning system and closed up all panels and doors. All doors were verified closed and locked. This airplane did not have the secondary latch screws normally found on this model aircraft because the door was not drilled for fasteners. Only primary spring latches were present. After this incident I advised the maintenance supervisor that a more precise check be added to the maintenance manual for doors lacking secondary latches or fasteners.
