Models named: Jetstream 4101. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to BAE Systems (Operations) Limited Model Jetstream 4101 airplanes, certificated in any category, all models, all serial numbers.

Unless already done, do the following actions for the left and right nose wheel attachments to the axle. (1) Within 3 months after the effective date of this AD, inspect the lock plate for damage (including excessive wear) and cracking, inspect the wheel nut for damage, and measure the gap between the inner flange of the outer cone and the end face of the axle to determine if parts are worn, in accordance with paragraph 2.B. of BAE Systems (Operations) Limited Service Bulletin J41-32-086, dated June 27, 2007. (2) If, during any inspection required by paragraph (f)(1) of this AD, any damage or cracking of the lock plate is found, before further flight, replace the lock plate with a new or serviceable part, in accordance with paragraph 2.B. of BAE Systems (Operations) Limited Service Bulletin J41-32-086, dated June 27, 2007. (3) If, during any inspection required by paragraph (f)(1) of this AD, any damage of the wheel nut is found, before further flight, replace the wheel nut with a new or serviceable part, in accordance with paragraph 2.B. of BAE Systems (Operations) Limited Service Bulletin J41-32-086, dated June 27, 2007. (4) If, during any measurement required by paragraph (f)(1) of this AD, the measured gap size is found to be less than 0.002 inch (0.05 mm), before further flight, replace any worn parts with new or serviceable parts, in accordance with paragraph 2.B. of BAE Systems (Operations) Limited Service Bulletin J41-32-086, dated June 27, 2007. Within 3,000 flight hours after doing the replacement, repeat the actions for the left and right nose wheel attachments to the axle that are required by paragraph (f)(1) of this AD. (5) If, during any measurement required by paragraph (f)(1) of this AD, the measured gap size is equal to or more than 0.002 inch (0.05 mm), repeat the actions for the left and right nose wheel attachments to the axle that are required by paragraph (f)(1) of this AD thereafter at intervals not to exceed the value indicated in Table 1 of this AD, depending on the exact finding. If, during any repeat inspection, the finding has changed to another value (see Table 1), adjust the new interval accordingly. Table 1—Repeat Inspection Intervals Measured gap size Repeat inspection interval in flight hours 0.002 inch to 0.005 inch inclusive (0.05/0.13mm) 500 Greater than 0.005 inch to less than or equal to 0.010 inch (0.13/0.25mm) 1,000 Greater than 0.010 inch to less than or equal to 0.020 inch (0.25/0.51mm) 2,000 Greater than 0.020 inch (0.51mm) 3,000 Note 1: Replacement of parts does not constitute terminating action for the inspection requirements of this AD. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: Although BAE Systems (Operations) Limited Service Bulletin J41-32-086, dated June 27, 2007, does not specify an inspection following the replacement of the left and right nose wheel attachment to the axle for measurements less than 0.002 inch, paragraph (f)(4) of this AD requires an inspection within 3,000 flight hours after replacing the part. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office.
