Models named: 777-200, -300ER series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to The Boeing Company Model 777-200 and -300ER series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 777-35-0041, dated April 8, 2016.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 72 months after the effective date of this AD: Replace the low-pressure oxygen flex hoses with new non-conductive low-pressure oxygen flex hoses in the gaseous passenger oxygen system in airplanes equipped with therapeutic oxygen, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-35-0041, dated April 8, 2016.

Unsafe condition

This AD was prompted by a determination that the low-pressure oxygen flex hoses in the gaseous passenger oxygen system in airplanes equipped with therapeutic oxygen can potentially be conductive. We are issuing this AD to prevent electrical current from passing through the low-pressure oxygen flex hoses in the gaseous passenger oxygen system, which can cause the flex hoses to melt or burn, and a consequent oxygen-fed fire in the passenger cabin.

Affected ADs

None.
