The fuselage frames in several other aircraft have also been found cracked, but to a lesser degree.\n\nItems 6 and 7 of the B200 Maintenance Manual Rev B7, 31 January 2003, Chart 201, “Priority Area Inspection Guide” currently require inspections in the area where the cracks in frame STA 207 were located. The threshold for these inspections at the time this AD was originally effective was 15,000 hours total time in service. The threshold for these inspections has now been revised to 10,000 cycles, with subsequent repeat inspections at 1,000 cycle intervals.\n\nBeechcraft 200 (Super King Air) Series Aeroplanes\n\nAD/BEECH 200/65 Amdt 1 (continued)\n\nThis amendment alters the AD compliance to align the threshold and repeat interval with that specified in the latest revision of the maintenance manual. The reporting requirement has also been altered to require the submission of a CASA Major Defect Report form if cracks are found in the fuselage frame at STA 207.\n\nThe original issue of this Airworthiness Directive became effective on 3 February 2000.\n\n![Signature of David Villiers](image.002.jpeg)  \n\nDavid Villiers\n\nDelegate of the Civil Aviation Safety Authority 2 May 2003\n\n![](image.001.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 21 May 2003.","sortOrder":0}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"This amendment changes the compliance thresholds and reporting requirement from the original AD: it reduces the inspection threshold from the prior figure used in the original AD (previously 15,000 hours per the maintenance guidance cited in the Background) to 10,000 cycles and mandates repeat inspections every 1,000 cycles, and it adds/clarifies the requirement to submit a CASA Major Defect Report when cracks are found.

(Applicability)\n- Inspections required: A detailed visual inspection of the right‑hand fuselage frame at Fuselage Station (STA) 207 and the adjacent frames, in the area between the lower longeron at Water Line 119 (below the windows) and the floor, to look for cracking. (Requirement 1)\n- Reporting required: If any cracks are found, the operator must report the finding to CASA on a Defect Report form, giving number of cracks, exact location (diagram if possible) and crack length. (Requirement 2)\n- Timing (compliance): Do the first inspection within 10 cycles after the aircraft reaches 10,000 total cycles in service, and then repeat inspections every 1,000 cycles. If cracks are found, the report must be submitted to CASA within 48 hours after the inspection. (Compliance 1–2)\n- Transitional note: If the operator has already been inspecting under the original version of the AD, the first inspection required by this amendment does not have to be done until 1,000 cycles after the last inspection performed under the original AD. If no prior inspection was done under the original AD, the new timing above applies. (Note)\n\n**Why the rule was issued (stated reason)\n\n- The AD says significant cracking was found in the fuselage frame at STA 207 on one aircraft and lesser cracking in others during investigation of an external skin crack. The AD amends the original directive to align the inspection threshold and repeat interval with the revised B200 Maintenance Manual (Chart 201, Priority Area Inspection Guide), which now specifies a threshold of 10,000 cycles with repeats every 1,000 cycles. The amendment also changes the reporting requirement to require submission of a CASA Major Defect Report form if cracks are found. (Background)\n\n**Who it affects and who pays\n\n- Primary burden falls on aircraft operators/owners of Beech 200 series aeroplanes. They must arrange and pay for the inspections, any follow‑up work (repairs/stripping/inspection access), and the time the aeroplane is out of service for inspection or repair. Maintenance organisations and licensed engineers perform the inspections and any required repair work and carry associated labour costs. CASA is the recipient of mandatory reports and retains regulatory oversight. (Applicability; Requirement; Compliance)\n\n**What decisions this forces (behavioural change)\n\n- Operators must: track cycles closely, schedule the mandated detailed inspections at the specified intervals, submit compulsory defect reports to CASA within 48 hours if cracks are found, and (where cracking is discovered) take whatever corrective maintenance is necessary (the AD requires reporting and inspection; repair actions will be driven by maintenance manual instructions, approved repair data or further CASA direction). (Requirement; Compliance)\n\n**Trade‑offs, costs and implementation considerations\n\n- Compliance costs: increased inspection frequency (earlier threshold and regular repeats) raises direct maintenance costs (labour and possibly parts) and indirect costs (aircraft downtime, potential schedule disruption). These costs are borne by operators. (Compliance)\n- Reporting burden: operators must prepare and lodge a defect report within 48 hours if cracks are found; this is an administrative cost and may trigger further regulatory action. (Requirement 2; Compliance 2)\n- Scope of action: The AD mandates inspection and reporting but does not in this text specify detailed repair/withdrawal‑from‑service criteria; operators will rely on the Maintenance Manual, approved repair schemes or separate instructions for corrective action. That creates dependence on the maintenance documentation and maintenance organisations to define the remedial steps. (Requirement; Background)\n- Implementation risk: the AD requires a \"detailed visual inspection\". Detectability depends on access, inspector skill, and inspection technique; missed cracks could persist until a later inspection. The AD reduces the interval and threshold to lower that risk, but inspection effectiveness still matters. (Requirement; Compliance)\n- Incentives and distributional effects: higher‑utilisation aircraft reach cycles sooner, so they will hit the threshold earlier than low‑utilisation examples; small operators with limited spares or tight schedules may face greater operational disruption. The requirement is uniform across all Beech 200s (Applicability) so it does not differentiate by operator size, but the relative burden differs by utilisation and fleet size. (Applicability; Compliance)\n- Regulatory reliance on manual: the AD aligns with the Maintenance Manual. Future changes to the manual could shift inspection policy; operators must follow the AD and the referenced maintenance instructions. (Background)\n\n**Short summary in one line\n\nThis AD requires regular, detailed visual inspections of the right‑hand fuselage frame at STA 207 on all Beech 200 aircraft (first inspection around 10,000 cycles with repeats every 1,000 cycles), and mandatory reporting to CASA if cracks are found; the amendment aligns the AD with the Maintenance Manual and tightens inspection timing.
