Airworthiness Directive · Amendment 39-15685 · Hawker Beechcraft Corporation Model BAe.125 Series 800A (including C-29A and U-125) Airplanes, and Hawker Beechcraft Model Hawker 800XP Airplanes
Hawker Beechcraft Corporation Model BAe.125 Series 800A (including C-29A and U-125) Airplanes, and Hawker Beechcraft Model Hawker 800XP Airplanes
This AD applies to Hawker Beechcraft Corporation Model BAe.125 series 800A (including C-29A and U-125) airplanes, and Hawker Beechcraft Model Hawker 800XP airplanes, certificated in any category; having serial numbers identified in Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008.
We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BAe.125 series 800A (including C- 29A and U-125) airplanes, and Hawker Beechcraft Model Hawker 800XP airplanes. This AD requires doing an inspection to determine the serial number and part number on the main landing gear (MLG) upper casing, and replacing the MLG assembly with a serviceable MLG assembly if necessary. This AD results from a report indicating that the MLG casings have received improper hydrogen embrittlement relief. We are issuing this AD to prevent a fracture of the MLG casings and a collapse of the affected MLG, which could adversely affect the airplane's continued safe flight and landing.
Comply with this AD within the compliance times specified, unless already done.
Within 30 days after the effective date of this AD, do the actions specified in paragraphs (f)(1) and (f)(2) of this AD.
(1) Do an inspection to determine whether an MLG upper casing, having a serial number and part number identified in Table 1 of the Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008, is installed.
(2) Do an inspection to determine whether an MLG upper casing, having a part number and serial number identified in paragraph 1.A.(2) of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008, is installed.
If any MLG upper casing having a serial number and part number identified in Table 1 of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008, or in paragraph 1.A.(2) of the service bulletin, is found during the inspection required by paragraph (f) of this AD: Within 30 days after the effective date of this AD, replace the MLG assembly with a serviceable MLG assembly, in accordance with the Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008.
Although the Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008, specify to contact the manufacturer, return spare parts to the manufacturer, and report accomplishment of the service bulletin to the manufacturer, this AD does not include those requirements.
(i) As of the effective date of this AD, no person may install, on any airplane, a MLG assembly having any serial number identified in Table 1 of the Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008.
(j) As of the effective date of this AD, no person may install, on any airplane, a MLG assembly having any serial number and part number identified in paragraph 1.A.(2) of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008.
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.
