The AD directs operators to carry out the work in accordance with BAe Alert Service Bulletin SB 52-A-JM7704 (Requirement). The work must be completed before 30 June 1990 (Compliance).\n\n- Who it affects: Owners/operators of BAe 3100 (Jetstream) aeroplanes with constructor numbers 757, 770–840, 842–847 and 850 (Applicability).\n\n- Why it matters (purpose and mechanistic effect): The Background states that a disconnection of the upper attachment of the restraint cable has prevented door opening. The AD therefore requires the corrective action so that the main door remains usable as an emergency exit (Background). The AD achieves this by mandating the specific corrective procedure set out in the manufacturer's alert SB (Requirement).\n\n- Who pays and who decides: The directive places responsibility on the owners/operators of the listed aircraft to have the required work done (Applicability; Requirement). The AD delegates the technical method to BAe's Alert SB, so the manufacturer-prescribed procedure determines what work is performed (Requirement).\n\n- Compliance mechanics, burdens and implementation risks: The AD sets a firm compliance deadline (Compliance). Because the AD references an external service bulletin rather than listing procedures in full, operators must obtain and follow that bulletin to comply (Requirement). The AD identifies a specific failure mode (upper attachment disconnection) as the reason for the action (Background). The document does not state costs, who performs the work, or inspection/verification steps; those practical details are handled by following the referenced BAe Alert (Requirement).\n\n- Limits and trade-offs visible from the text: The AD is limited in scope to particular constructor-numbered aeroplanes (Applicability). It mandates corrective action to keep the main door available as an emergency exit (Background), trading off operator time and expense for the safety objective stated. The AD does not itself specify alternative compliance options, relief, or compensation; it requires the actions described in the BAe Alert within the stated timeframe (Requirement; Compliance)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable","history":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable/history","analysis":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable/analysis","conflicts":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable/conflicts","importantCases":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable/important-cases","documents":"/api/acts/ad-jetstream-35-passenger-crew-door-restraint-cable/documents"}}
