A faulty or poorly positioned stall warning could fail to alert a pilot in time, potentially leading to loss of control. This AD mandates a fix to prevent accidents.\n\n**Who must comply:** Anyone operating the affected Piper PA-36-285 model aircraft.\n\n**When:** The work had to be completed within 100 hours of flight time after 29 November 1974.\n\n**How to comply:** Follow either Piper Service Bulletin No. 418 or the equivalent US Federal Aviation Administration AD 74-21-02 for instructions on relocating the detector."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation","history":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation/history","analysis":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation/analysis","conflicts":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation/conflicts","importantCases":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation/important-cases","documents":"/api/acts/ad-pa-36-2-stall-warning-detector-relocation/documents"}}
