The work must follow the technical instructions in Rockwell International Service Letter SL-114-11.\n\n**Deadline:**\nThe installation had to be completed within 100 hours of flight time after 30 June 1978.\n\n**Why it matters:**\nThis safety fix prevents the landing gear from failing to extend or retract properly — a defect that could cause the landing gear to collapse during landing.\n\n**Who is affected:**\nAnyone owning, operating, or maintaining the specific aircraft models listed above."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation","history":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation/history","analysis":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation/analysis","conflicts":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation/conflicts","importantCases":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation/important-cases","documents":"/api/acts/ad-rock-114-7-landing-gear-retract-cylinder-retainer-and-rod-end-lockwasher-installation/documents"}}
