Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes, certificated in any category, serial numbers 201 through 290 inclusive.
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires a one-time detailed or borescope inspection of the left- and right-hand inboard vent holes for debris or obstructions, and repair if necessary. This AD was prompted by a report indicating that an inboard vent tube hole was completely covered with sealant, which blocked airflow through the vent. Under these conditions, the rise of internal pressure during pressure fueling or due to thermal expansion is sufficient to damage the wing. We are issuing this AD to detect and correct compromised integrity of the wing structure.
Before further flight: Do a one-time detailed or borescope inspection of the left- and right-hand inboard vent holes for debris and obstructions, in accordance with the Accomplishment Instructions of Gulfstream G150 Alert Service Bulletin 150-28A-146, dated June 22, 2012. If any debris or obstruction is found, before further flight, repair in accordance with a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil Aviation Authority of Israel (CAAI) (or its delegated agent).
(1) Submit a report of positive findings of the inspection required by paragraph (g) of this AD to Gulfstream Aerospace CMP, fax 800-944-1775 or 912-963-0265, at the applicable time specified in paragraph (h)(1)(i) or (h)(1)(ii) of this AD. The report must include the inspection date and results, a description of any finding, the airplane serial number, and the number of flight hours and landings on the airplane.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 10 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 10 days after the effective date of this AD.
(2) A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES-200.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
