GROUNDED AIRCRAFT

An aircraft requiring modification or repair may become "grounded" until the necessary work has been completed and the aircraft is once again fit for flight.

In many cases, the work is concluded within a few days and the Certificate of Airworthiness (CofA) or Permit to Fly will be re-validated by the maintenance organisation responsible.

However, in some cases, the aircraft may be grounded for many months. In these circumstances, the aircraft owner may wish to surrender the CofA or Permit to Fly in order to receive a pro-rata refund on the validation cost.

Before this is decided, the following information should be considered:

• The aircraft may not be flown until a new CofA or Permit to Fly is issued.

• Refunds made will be relative only to the cost of CofA or Permit validation- investigation costs will not be refunded.

• If a CofA or Permit to Fly is surrendered, the next document issued will be a subsequent issue- not a renewal. The fee for a subsequent issue is higher than that for a renewal.

For further advice, please contact the Applications and Approvals Department.

If technical advice is required for urgent operational reasons out of normal office hours, for UK Air Operator Certificate (AOC) holders, the CAA will endeavour to assist wherever possible.

Please note, in order for the CAA to issue a Permit to Fly on a damaged aircraft, the associated Flight Conditions must be approved by EASA. Please refer to the EASA website for further details.
