Airworthiness Directive · Amendment 39-21165 · Fuselage
Gulfstream Aerospace LP Airplanes
This AD applies to certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes, certificated in any category, as identified in Civil Aviation Authority of Israel (CAAI) AD ISR-I-53-19-10-5, dated October 10, 2019 (“Israeli AD ISR-I-53-19-10-5”).
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes. This AD was prompted by a report of inadequate clearance between the fuel probes and forward fuel tank structure. This AD requires measuring the clearance between certain fuel probes and the forward fuel tank structure, and reinstalling the probes if necessary, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Israeli AD ISR-I-53-19-10-5.
(1) Where Israeli AD ISR-I-53-19-10-5 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Israeli AD ISR-I-53-19-10-5 requires operators to “check... clearance between fuel probes and forward fuel tank structure,” this AD requires measuring the specified probes' distance to the adjacent skin.
(3) Where Israeli AD ISR-I-53-19-10-5 requires operators to “adjust clearance” for the corrective action, this AD requires reinstallation of the probe at the correct distance.
(4) Israeli AD ISR-I-53-19-10-5 requires compliance “at the next suitable planned maintenance inspection within the next 36 months.” This AD requires compliance within 36 months after the effective date of this AD.
(5) The rework (reinstallation of the fuel probes at the correct distance) required for inadequate clearance must be done before further flight after the measurement.
