What to do
Operators of Boeing 777-300ER airplanes must replace the water filter assembly in Jamco steam ovens, part numbers ASN2001-1 and ASN2001-12, within 375 days from June 25, 2018. No installation of affected steam ovens is allowed without this modification. Maintenance personnel should follow Boeing Service Bulletin 777-25-0617 dated June 6, 2014, for the replacement procedure and ensure documentation of compliance.
Summary
The Federal Aviation Administration Airworthiness Directive 2018-12-04 is a final rule addressing certain Boeing 777-300ER series airplanes. It mandates the replacement of the water filter assembly in Jamco steam ovens, part numbers ASN2001-1 and ASN2001-12, to prevent hot water from escaping when the oven door is opened. This directive aims to mitigate the risk of injury to cabin crew caused by heated water release from the steam oven cavity.
What changed
This new airworthiness directive requires operators of Boeing 777-300ER airplanes to replace the existing water filter assembly in specified Jamco steam ovens with an improved assembly featuring a larger screen. The change addresses a previously reported unsafe condition where foreign objects could block the solenoid valve, allowing water to enter and heat in the oven cavity. The directive also prohibits installation of affected steam ovens unless the replacement is performed.
Why it matters
This directive is critical for aviation professionals because it addresses a safety hazard that could cause injury to cabin crew during normal operation of the steam ovens. Operators and maintenance teams must ensure compliance to maintain aircraft safety and regulatory adherence. Failure to comply could result in unsafe conditions and potential liability issues during inspections or incidents.
