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. For aircraft listed in Group A or Group B of the applicability part of this Directive, install retainer clip part number 104687-002 in accordance with Part II of SB No. 1139A, dated 9 April 2004. |\n| | Note: Corrected FAA AD 2004-14-12 Amdt 39-13721 refers. |\n| Compliance: | 1. Within 25 hours time in service after 11 August 2004.2. Within 100 hours time in service after 11 August 2004.The compliance times remain unchanged by this issue. |\n| | This Amendment becomes effective on 17 March 2005. |\n| Background: | The FAA received a report that a Model PA-28-181 aircraft crashed after the pilot lost control of the ailerons and elevator. 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-32/83 Amdt 1","sectionType":"part","heading":"AD/PA-32/83 Amdt 1","content":"## AD/PA-32/83 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":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.

This caused the control wheel to spin freely, making the pilot lose control of the ailerons (wing flaps that turn the plane) and elevator (which controls pitch up and down).\n\n**Who must act:**\n- **Group A aircraft:** Specific Saratoga II HP and TC models with serial numbers listed — must inspect the screw and nut plate, replace if faulty, and use thread-locking compound when reassembling\n- **Group A and B aircraft:** All listed models — must install a retainer clip as an additional safety measure\n\n**When it must be done:**\n- Inspections and screw replacements: 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 is a critical flight safety issue. A loose control wheel means the pilot cannot control the aircraft's direction or altitude, which can lead to a crash.
