AD: MD Helicopters, Inc. (MDHI) Helicopters

AD NUMBER: 2013-20-16

PRODUCT: MDHI Model MD900 helicopters with certain main rotor blade (MRB) retention bolts (bolts) installed.
SUBJECT: Airworthiness Directive 2013-20-16
ACTION: Final Rule

SUMMARY: This AD requires a daily check of the position of each bolt, a daily check and a repetitive inspection for a gap in each bolt, and, if necessary, removing and inspecting the bolt for a crack and replacing any cracked bolt with an airworthy bolt.

This AD was prompted by multiple reports of in-service bolt failures. The actions are intended to prevent failure of a bolt, which could lead to loss of MRB structural integrity and subsequent loss of control of the helicopter.

DATES: This AD is effective December 5, 2013.
