Introduction:
The purpose of this Special Airworthiness Inform ation Bulletin (SAIB) is to provide valuable information to owners/operators of Raytheon (Beech) models as listed below. The applicability and model serial numbers were also listed in Airworthiness Directive (AD) 93-24-03.
Models Serial Numbers 35-33, 35-A33, 35-B33, 35-C33, E33, F33 and G33 CD-1 through CD-1304 35-C33A, E33A, and F33A CE-1 through CE-1425 E33C and F33C CJ-1 through CJ-179 36 and A36 E-1 through E-2518 A36TC and B36TC EA-1 through EA-500
Raytheon Aircraft Company (RAC) issued Service Bulletin (SB) 2333, titled “Flight Controls – Inspection of Rudder Forward Spar for Cracks” in October 1989. This SB provided an inspection and repair procedure for RAC’s Model 33 and M odel 36 to determine any cracks in the rudder forward spar.
Background:
Following SB 2333, the FAA issued AD 90-11-04. Supplemental Type Certificate (STC) SA 4899NM approved a Spacecraft Machine Produc t (SMP) reinforcement bracket as a replacement bracket. FAA issued AD 91-23-07 to in clude the use of SMP brackets. Later, RAC designed a kit (Kit No. 33-6001-1 S) to strengthen the rudder and added inspection covers at the upper and center hinges of the rudder. RAC i ssued SB 2333, Revision 1 in November 1991 to include the use of this kit. FAA issued AD 92-15-06 to reflect changes made by SB 2333, Revision
1. AD 93-24-03 superseded AD 92-15-06 to include the procedure to modify the rudder found to be cracked near the center hinge.
Recommendations:
AD 93-24-03 requires inspection of rudder forwar d spars within 100 hours of Time-In-Service (TIS) after initial 1000 hours of TIS. A Bonanza owner/operator reported that this initial period is too long to provide an efficient means for detec ting cracks in acrobatic category models, as these airplanes often perform high ‘g’ maneuvers and ar e subjected to high loads. The FAA, as a precaution, highly recommends inspection of the rudder forwar d spars of the acrobatic category airplanes for cracks at the next scheduled inspection, unless already accomplished. The instructions given in AD 93-24-03 should be followed.
2 CE-00-21 The same Bonanza owner reported difficulty and long lead-time in obtaining SMP brackets. To install a bracket as suggested in AD 93-24-03 (b )(3), the FAA recommends using a SMP-1 bracket or DW-1 bracket. If a crack is found in the cen ter bracket, we recommend following instructions in AD 93-24-03 (c)(3) or installing a DW-2 center br acket. Both DW-1 and DW-2 brackets are approved by FAA in STC SA0044LA and the use of these brackets is accepted by FAA as an Alternate Means of Compliance (AMOC) to AD 93-24-03. The STC holder for DW brackets is Mr. Dick Wilson, P.O Box 2521, Palos Verdes, CA, 90274; telephone: (310) 326-8516.
