What happens now?

The affected parts will be removed and taken to Sikorsky research laboratories for detailed examination.

Currently, the aircraft has a 500 hr recurring inspection in this area. Sikorsky will shortly issue an Alert Service Bulletin (ASB) which will reduce the number of hours between inspections of the affected area. This will be followed up by a proactive modification to the frames that will eliminate the issue.

Incident Recommendations

It is possible that the Federal Aviation Administration (FAA) and EASA may then decide to issue an Airworthiness Directive which would require helicopter operators to comply with certain conditions.
