Applies to Model DHC-8-100 series airplanes, Serial Numbers 1 through 113, certificated in any category. Compliance required as indicated, unless previously accomplished. To prevent inadvertent unfeathering of the propeller, accomplish the following: A. Within 24 hours after the effective date of this AD, insert the following note into the Emergency Operating Procedures Section of the Airplane Flight Manual (AFM) [PSM-1-81- 1A(FAA)], and alert all flight crews. This may be accomplished by inserting a copy of this airworthiness directive into the front of the Emergency Operating Procedures Section (Section 4) of the AFM: "NOTE: Should an engine failure or fire after V1 occur: Ensure that the emergency procedures of paragraphs 4.1.2., 4.2.1., and 4.2.2 of PSM 1-81-1A(FAA) are followed. The ENGINE SHUTDOWN check, paragraph 4.2.1., is not to be commenced until entering the third segment of the takeoff path. On commencement of the ENGINE SHUTDOWN or ENGINE FIRE (IN FLIGHT) check, paragraph 4.2.1. or 4.2.2, respectively, the check should be completed sequentially and uninterrupted to its conclusion." B. Installation of the modification to the propellers-autofeather latching logic wiring, in accordance with de Havilland Service Bulletin 8-61-12, Revision A, dated October 28, 1988, constitutes terminating action for the requirements of paragraph A., above, and the required "NOTE" may be removed from the AFM. C. An alternate means of compliance which provides an acceptable level of safety may be used when approved by the Manager, New York Aircraft Certification Office, FAA, New England Region. All persons affected by this directive who have not already received the appropriate service information from the manufacturer, may obtain copies upon request to Boeing of Canada, Ltd., de Havilland Division, Garrett Boulevard, Downsview, Ontario M3K 1Y5, Canada.

2016-23-07: We are superseding Airworthiness Directive (AD) 2013-02-08 for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2013-02-08 required inspection of the trunnions and upper and lower pins of the horizontal stabilizer trim actuator (HSTA), and replacement or re-identification if necessary; and revision of the maintenance program to include safe life limits and inspection requirements for the HSTA. This new AD requires certain actions related to the trunnions and pins for the HSTA, revising the maintenance or inspection program, and removing certain airplanes from the applicability. This AD was prompted by a determination that not all affected attachment pins and trunnions were included in the inspections required by AD 2016-02-08, and that incorrect attachment hardware may have been used in replacements on certain airplanes. We are issuing this AD to address the unsafe condition on these products.
2018-19-33: We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
2016-23-08: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-400 series airplanes. This AD was prompted by reports of cracks in the upper chord of the overwing stub beams at body station (STA) 578 emanating from the rivet location common to the crease beam inner chord and the overwing stub beam upper chord. This AD requires repetitive inspections for cracking, and related investigative and corrective actions if necessary. We are issuing this AD to prevent the unsafe condition on these products.
2016-24-01: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes; and Model DHC-8-200 and -300 series airplanes. This AD was prompted by a report of heat damage found on a nacelle firewall after an unsuccessful engine ground start and several events of heat damage found on direct current starter/generator terminal block assemblies. This AD requires an inspection to detect damage on the nacelle firewalls and the terminal block assemblies and to make sure the insulating sleeves are installed and have no damage, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

Compliance: Required as indicated, unless accomplished previously. To prevent reduced braking authority and reduced directional control of the airplane while it is on the ground, accomplish the following: (a) Within 30 days after the effective date of this AD, conduct an inspection of the rudder (brake) pedal assemblies, to verify installation of retainer rings, part number (P/N) MS16624-1075, in accordance with Fokker Service Bulletin SBF100-27-047, Revision 1, dated February 9, 1993. (1) If all of the retainer rings are installed correctly, no further action is required by this AD. (2) If any retainer ring is not installed, or is not installed correctly, prior to further flight, install retainer ring, P/N MS16624-1075, in accordance with the service bulletin. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The inspection and necessary installation shall be done in accordance with Fokker Service Bulletin SBF100-27-047, Revision 1, dated February 9, 1993, which contains the following list of effective pages: Page Number Revision Level Shown on Page Date Shown on Page 1 1 February 9, 1993 2-4 Original August 28, 1992 This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51.

2024-19-11: The FAA is adopting a new airworthiness directive (AD) for all Robinson Helicopter Company Model R44 and R44 II helicopters. This AD was prompted by reports of a fractured clutch shaft forward yoke (yoke) on the main rotor (M/R) drive due to fatigue cracking. This AD requires visually inspecting a certain part-numbered flex plate assembly (flex plate) and certain part-numbered yokes, including each flex plate bolt, and depending on the inspection results, removing an affected part from service and replacing an affected part with an airworthy part. This AD also requires removing a certain part-numbered yoke from service after accumulating a certain number of hours time-in-service (TIS) or a certain number of years, or as an alternative to removing the part from service, performing a 10x or higher power magnification visual inspection and, if needed, a magnetic particle inspection. The FAA is issuing this AD to address the unsafe condition on these products.
