AD 2021-10-27 Requires Replacing Each Honeywell Emergency Light Power Unit Having A Certain Part Number
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ series airplanes.
This AD was prompted by a report indicating that during a routine battery capacity check on the emergency light power units, the printed circuit boards (PCBs) for certain power units were found to show signs of burning. This AD requires replacing each Honeywell emergency light power unit having a certain part number with a serviceable emergency light power unit. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective June 17, 2021.
Supplementary Information: The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0237, dated October 28, 2020 (EASA AD 2020-0237) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ series airplanes. You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-0138.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ series airplanes. The NPRM published in the Federal Register on March 15, 2021 (86 FR 14283). The NPRM was prompted by a report indicating that during a routine battery capacity check on the emergency light power units, the PCBs for certain power units were found to show signs of burning. The NPRM proposed to require replacing each Honeywell emergency light power unit having a certain part number with a serviceable emergency light power unit. The FAA is issuing this AD to address heat damage of the PCBs, which could lead to battery discharge and possibly result in lack of power supply to the emergency light units when needed. See the MCAI for additional background information.
