Federal Aviation Administration July 19, 2019 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Ipeco Pilot and Co-Pilot Seats
Document Number: 2019-15413
Type: Proposed Rule
Date: 2019-07-19
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede airworthiness directive (AD) 2017-22-02, which applies to certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2017-22-02 requires modification and re- identification of the affected seats. Since the FAA issued AD 2017-22- 02, Ipeco has received reports that the tracklock spring modification required by AD 2017-22-02 does not adequately address the issue of unexpected seat movement during takeoff and landing and the FAA also determined the need to add additional seat part numbers (P/Ns) to the applicability. This proposed AD would continue to require modification and re-identification of the affected seats. This proposed AD would also require initial and repetitive inspections of the affected tracklock springs and, depending on the findings, replacement of the tracklock springs with a part eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2019-15360
Type: Rule
Date: 2019-07-19
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by reports indicating there is a possibility of excessive error in the signal generated by the angle of attack (AOA) transducer. This AD requires replacing certain AOA transducers. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2019-15358
Type: Rule
Date: 2019-07-19
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 airplanes. This AD was prompted by reports of cracking in the lower lobe skin panel assemblies of the fuselage and an evaluation by the design approval holder (DAH) indicating that these assemblies are subject to widespread fatigue damage (WFD). This AD requires replacement of lower lobe skin panel assemblies, detailed inspections for scribe lines, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
