Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0 1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):
2016-22-03 Bombardier, Inc.: Amendment 39-18692; Docket No. FAA- 2015-8464; Directorate Identifier 2015-NM-050-AD.
(a) Effective Date
This AD is effective November 30, 2016.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 61, Propellers/ propulsors.
(e) Reason
This AD was prompted by a revision by the manufacturer to the Certification Maintenance Requirements (CMR) of the Airworthiness Limitation Items (ALI), in the Maintenance Requirement Manual (MRM), that introduces a new CMR task that requires repetitive operational checks of the propeller overspeed governor. We are issuing this AD to prevent dormant failure of the propeller overspeed governor, which may lead to a loss of propeller overspeed protection and result in high propeller drag in flight.
(f) Compliance
Comply with this AD within the compliance times specified, unless already done.
(g) Maintenance Program or Inspection Program Revision
Within 30 days after the effective date of this AD, revise the maintenance program or inspection program, as applicable, to incorporate an operational check of the propeller overspeed governor, CMR task number 612000-109, to be performed every 200 flight hours, using a method approved by the Manager, New York Aircraft Certification Office (ACO), ANE-170, FAA.
Note 1 to paragraph (g) of this AD: CMRtask number 612000-109, Operational Check of the Propeller Overspeed Governor, in Bombardier Q400 Dash 8 Temporary Revision (TR) ALI-129, dated September 3, 2013, is an additional source of guidance for the operational check of the propeller overspeed governor specified in paragraph (g) of this AD.
(h) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO, ANE-170, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly

Before using any approved AMOC,notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, New York ACO, ANE-170, FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA Design Approval Organization (DAO).
