Defense Logistics Agency Aviation Retained Excessive V-22 Osprey Spare-Parts Inventory



The objective of the audit was to determine whether DoD effectively managed Government-owned V-22 spare parts before procuring the same parts from private contractors and whether DoD properly accounted for Government-owned V-22 inventory managed by private contractors.


The Defense Logistics Agency (DLA) Aviation did not effectively manage Government-owned V-22 Osprey spare parts. For 22 of 53 spare parts that we nonstatistically selected for review, DLA Aviation retained spare-parts inventory that was excessive.

This occurred because DLA Aviation:

  • did not evaluate the reasonableness of V-22 Osprey spare-parts inventory quantities, and
  • forecasted and purchased excessive inventory of V-22 Osprey spare parts.

As a result, DLA Aviation retained excessive inventory valued at $8.7 million. In addition, it will cost DLA Aviation approximately $0.7 million in holding costs over the next 5 years to store and retain the excessive inventory.


We recommend that the Director, DLA:

  • evaluate the reasonableness of V-22 Osprey spare-parts inventory quantities to ensure they do not retain or procure excessive inventory;
  • review inventory identified as economic retention stock and contingency retention stock and determine whether it was properly categorized. In addition, document its retention and approval decisions, if applicable; re-categorize the inventory, as appropriate; and initiate the review and disposal process for V-22 Osprey spare parts categorized as potential reutilization stock; and
  • establish a plan for conducting periodic reviews of forecasting results to ensure DLA Aviation officials do not purchase excessive V-22 Osprey spare-parts inventory.
