Aviation Law and Regulations

Most countries are member of the International Civil Aviation Organization (ICAO) and as such have signed the "Chicago Convention 1944" (111 pages, 2 Mb). Aviation rules and regulations in member countries are based on the recommendations of the ICAO.

The United Kingdom CAA has published EASA emergency airworthiness directive EAD-2012-0009-E regarding Rotax 912 S2, 912 S3 and 914 F2 engines: Engine Oil – Oil Pump and Attachment Bolts – Inspection.

EASA Emergency Airworthiness Directive

Excerpt from the document:

During a production quality review, a deviation in the assembly process of the oil pump attachment bolts has been detected, which may have resulted in a latent defect on a limited number of engines. The affected bolts may not have been tightened to the correct torque value, i.e. not in accordance with the specification.

This condition, if not corrected, could lead to oil leaks and irregularities in the oil supply, possibly resulting in uncommanded in-flight engine shutdown and forced landing, damage to the aeroplane and injury to occupants.
