Recommendation Date
Recipient Name
On 14 December 2017, the Commission recommended to the Director of Civil Aviation that he consult with the original equipment manufacturer when considering a modification or supplemental type certificate which, if approved, could result in any aircraft being used in a way that is significantly different from that which the manufacturer originally modelled and used as the basis for determining component fatigue lives and the aircraft maintenance programme

In considering the draft recommendation, the CAA refers the Commission to the Directors response on 10 October 2017 where, the CAA considers that original equipment manufacturers are unlikely to release proprietary and commercially sensitive information on the majority of occasions when they are asked to do so.
However, the Director is prepared to accept the recommendation on the basis that the CAA will seek a manufacturer’s advice on the utilisation of an aircraft if it is considered that a modification or supplemental type certificate may place the aircraft’s operations outside of that originally intended.
