For aircraft listed in Group A of the applicability part of this Directive, with the exception of aircraft listed in Group A that are already modified in accordance with the New Piper Aircraft Service Bulletin (SB) No. 1139, dated 28 August 2003; accomplish the following in accordance with Part I of SB No.1139A dated 9 April 2004:a. Inspect the control wheel attachment screw for proper thread engagement (minimum one thread showing past the end of the nut plate), and replace the screw before further flight if insufficient thread engagement is found.b. Inspect the nut plate for sufficient locking characteristics. If the screw can be fully inserted into the nut plate by hand (one thread showing past end of nut), then replacement of the nut plate is required before further flight.c. Reassemble the control wheel onto the control wheel shaft and install the attachment screw using Loctite thread-locking compound.2.

Investigation revealed that the left control wheel single attachment screw had unscrewed from its nut plate, which resulted in the control wheel spinning freely on the control column. Further investigation revealed the screw was too short and the nut plate lacked proper locking characteristics.Amendment 1 is issued in response to the issue of a corrected copy of the related FAA AD, which corrects certain parts of the text. The only part requiring correction of this Directive was Requirement 1. text, “Part I of SB No. 1139 dated 9 April 2004” which was changed to “Part I of SB No. 1139A dated 9 April 2004”. |\n\n![](image.001.png)  \nDavid Punshon  \nDelegate of the Civil Aviation Safety Authority\n\n4 February 2005","sortOrder":0},{"sectionNumber":"AD/PA-46/32 Amdt 1","sectionType":"part","heading":"AD/PA-46/32 Amdt 1","content":"## AD/PA-46/32 Amdt 1","sortOrder":1},{"sectionNumber":"Control Wheel Attachment","sectionType":"part","heading":"Control Wheel Attachment","content":"## Control Wheel Attachment","sortOrder":2},{"sectionNumber":"3/2005","sectionType":"part","heading":"3/2005","content":"## 3/2005","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This is Amendment 1 to an existing Airworthiness Directive.

A screw that holds the control wheel to the steering column can come loose or be too short, causing the pilot to lose control of the aircraft — which has already caused at least one crash.\n\n**Who must act:**\n- **Group A aircraft** (older serial numbers): Must inspect the attachment screw and nut plate for proper fit and locking ability, replace if faulty, and reinstall using thread-locking compound. They must also install a retainer clip.\n- **Group B aircraft** (newer serial numbers): Only need to install the retainer clip.\n\n**When:**\n- Inspections and screw fixes: Within 25 flight hours after 11 August 2004\n- Retainer clip installation: Within 100 flight hours after 11 August 2004\n\n**Why it matters:**\nThis prevents the control wheel from spinning freely or detaching during flight, which would make the aircraft uncontrollable.
