If the aircraft is equipped with floats or snow skis at the time of the initial inspection required by this Directive, inspect following the initial inspection and repetitively inspect thereafter; at the times specified in the compliance section of this Directive.b. If the floats or snow skis are removed from the aircraft at any time following the initial inspection, inspect following the last inspection; at the time specified in the compliance section of this Directive.c.

Continue these repetitive inspections until removal of floats or snow skis, at which time Requirement 2.b. must be followed.2.b. Inspect no later than 48 months following the last inspection. After the inspection following removal of floats or snow skis, no further inspections are required unless floats or snow skis are re-installed at a later date, at which time Requirement 2.c. must be followed.2.c. Inspect no later than 48 months following the last inspection or before further flight after installation of floats or snow skis, whichever occurs later, and repetitively inspect thereafter at intervals not to exceed 48 months. Continue these repetitive inspections until removal of floats or snow skis, at which time Requirement 2.b. must be followed. |\n| | This Airworthiness Directive becomes effective on 6 June 2008. |\n\n| Background: | This Directive results from data collected from an accident involving a Taylorcraft Model BF12-65 aircraft. The wing separated from the aircraft after the wing lift strut attach fitting failed due to corrosion. The actions required by this Directive are intended to detect and correct corrosion or cracks in the attach fittings, which could result in failure of the attach fittings and lead to wing separation and loss of control. |\n| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nDavid Villiers \nDelegate of the Civil Aviation Safety Authority\n\n26 May 2008","sortOrder":0},{"sectionNumber":"AD/TAYLORCRAFT/2","sectionType":"part","heading":"AD/TAYLORCRAFT/2","content":"## AD/TAYLORCRAFT/2","sortOrder":1},{"sectionNumber":"Wing Lift Strut Attach Fittings","sectionType":"part","heading":"Wing Lift Strut Attach Fittings","content":"## Wing Lift Strut Attach Fittings","sortOrder":2},{"sectionNumber":"8/2008 DM","sectionType":"part","heading":"8/2008 DM","content":"## 8/2008 DM","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":5,"scope_assessment":{"changed":true,"description":"This Directive explicitly extends application to all listed Taylorcraft models, including those not covered by Taylorcraft Aviation Service Bulletin No.2007‑002, and states the Directive takes precedence over the Service Bulletin where they differ (Applicability).
