NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE APPLICABLE TO BEECH MODEL 35, 35R, A35, AND B35 AIRPLANES REQUIRING: (1) AT THE NEXT ANNUAL OR 100-HOUR INSPECTION, WHICHEVER OCCURS FIRST, AND AT ANY TIME THE RUDDERVATORS ARE REPAIRED OR REPAINTED, A CHECK OF RUDDERVATOR UNDERBALANCE (TAIL HEAVINESS) TO ENSURE THAT IT IS WITHIN THE MANUFACTURER'S SPECIFIED LIMITS OF 16.8 TO 19.8 INCH-POUNDS, AND (2) AT THE NEXT ANNUAL OR 100-HOUR INSPECTION, WHICHEVER OCCURS FIRST, AND AT EACH ANNUAL AND 100-HOUR INSPECTION THEREAFTER, AN INSPECTION OF THE AFT FUSELAGE BULKHEADS AT STATIONS 256.9 AND 272.0 (STABILIZER FRONT AND REAR SPAR ATTACHMENT BULKHEADS) FOR EVIDENCE OF CRACKS, DISTORTION, LOOSE RIVETS, OR OTHER DAMAGE, AND THE FUSELAGE SKIN IN THE VICINITY OF THE BULKHEADS FOR EVIDENCE OF WRINKLES OR CRACKS. ANY DAMAGE FOUND SHOULD BE REPAIRED BEFORE FURTHER FLIGHT.
In plain language (FlightFinder summary)
The FAA is asked to issue an airworthiness directive for Beech Model 35, 35R, A35, and B35 airplanes. The directive would require checking ruddevator underbalance (tail heaviness) to remain within 16.8 to 19.8 inch-pounds at the next annual or 100-hour inspection, and whenever the ruddevators are repaired or repainted. It would also require inspecting the aft fuselage bulkheads at stations 256.9 and 272.0 for cracks, distortion, loose rivets, or other damage, and the surrounding skin for wrinkles or cracks, at the next annual or 100-hour inspection and at each subsequent one; any damage must be repaired before further flight.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
