Avoid Prolonged Slips (20 Seconds or More) with Fuel Tanks Less Than Half Full” (Requirement 1).  \n- Permits the owner or operator to make and certify the placard installation themselves, provided letters are at least one eighth inch high (Note to Requirement 1).  \n- Requires removal, where fitted, of an older placard that read: “CAUTION - To Prevent Fuel Flow Interruption Due to Gravity or Centrifugal Force, Select the High-Wing Tank in Slips and Inside Tank During Turning Take-offs” (Requirement 2).  \n- Gives a compliance deadline of within 100 hours time-in-service after 29 April 1970 (Compliance).  \n- References FAA AD 70-3-5 (Note under Requirement 2).\n\nWho this affects\n\n- Owners and operators of Beechcraft Model 36 aeroplanes with serial numbers E-1 through E-184 that have not been retrofitted with anti-slosh main fuel tanks (Applicability).  \n- Aircraft that already display the older caution placard specified in Requirement 2 (they must have that placard removed).\n\nWhy it matters (stated purpose and practical effects)\n\n- The instrument-panel placard prescribes specific operational restrictions for pilots (prohibiting certain turning-type take-offs and advising against prolonged slips with low fuel), and so directly affects pilot behaviour while operating affected aeroplanes (Requirement 1).  \n- The removal requirement eliminates conflicting or previous cautions about tank selection during slips and turning take-offs (Requirement 2).  \n- The directive therefore changes the displayed operational instructions available to pilots and mandates which instruction must be visible in the cockpit.\n\nCosts, incentives, trade-offs, implementation risks and compliance burden (source-grounded)\n\n- Who pays: The owner or operator is given express responsibility to make and certify the installation of the new placard if they choose to do the work themselves (Note to Requirement 1). That implies out-of-pocket cost for producing and affixing the placard or the cost of having someone else do that work.  \n- Compliance burden: Installation (or arranging installation) of a small placard and, where present, removal of an older placard. The directive specifies minimum letter size (one eighth inch) but otherwise prescribes a single, discrete physical action (Requirement 1; Note to Requirement 1; Requirement 2).  \n- Timing constraint: The rule must be complied with within a defined service-time window (100 hours after 29 April 1970), which imposes a schedule on the owner/operator regardless of immediate operational plans (Compliance).  \n- Incentives and behaviour change: The placard text explicitly instructs pilots to avoid or prohibit particular manoeuvres in specified fuel conditions, so pilots are given a binding instruction to change in-flight behaviour when using affected aircraft (Requirement 1).  \n- Information substitution: Requiring removal of the older caution placard (Requirement 2) replaces one set of cockpit instructions with another; this may change what pilots rely on during operations.  \n- Administrative discretion: The directive specifies actions and formats (letter size), leaving little room for regulatory discretion in execution beyond certifying the installation.  \n\nEffects on private choices and market factors (source-grounded)\n\n- Private operation and ownership: The directive places a compliance task on individual owners/operators of particular aircraft models and serial ranges (Applicability; Note to Requirement 1).  \n- Competition and prices: The instrument prescribes a physical placard and removal of another placard. There is no text in the source that creates new fees, subsidies, licensing limits, ownership restrictions, or ongoing regulatory reporting that would directly affect market competition, prices, or firm productivity beyond the one-off compliance action.  \n- Independent businesses (maintenance shops): Owners may choose to have a maintenance provider install the placard; the AD allows owners/operators to do it themselves, so it does not mandate use of a certified third party for the placard installation (Note to Requirement 1).  \n\nImplementation notes and cross-reference\n\n- The AD explicitly references FAA AD 70-3-5 (Note under Requirement 2), indicating the change aligns with that FAA directive.  \n\nSource citations\n\n- Applicability; Requirement 1; Note to Requirement 1; Requirement 2; Compliance; Note referencing FAA AD 70-3-5."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-5-fuel-system-placards","history":"/api/acts/ad-beech-36-5-fuel-system-placards/history","analysis":"/api/acts/ad-beech-36-5-fuel-system-placards/analysis","conflicts":"/api/acts/ad-beech-36-5-fuel-system-placards/conflicts","importantCases":"/api/acts/ad-beech-36-5-fuel-system-placards/important-cases","documents":"/api/acts/ad-beech-36-5-fuel-system-placards/documents"}}
