What these are... | |||
| These are the DW-1 and DW-2 Rudder Hinge Brackets developed back in the early 90's by Debonair Owner and Engineer Dick Wilson in response to AD 93-24-03. Straight tail Bonanzas and Debonairs were experiencing cracking of the rudder spar so an AD was established giving owners only two methods of compliance. 1) Remove and inspect the rudder every 500 hours or 2) An expensive kit from Beechcraft that replaces the spar and provides inspection holes. |
| What they do... |
|
||||
| These replace the original simple rudder hinge brackets (left) with Dick Wilson's redesiged brackets (right) which shifts the load away from the spar and prevents cracking. |
| Why you need them... | |||
|
Installing these brackets doesn't remove the AD (only the FAA can do
that) but what it does is eliminate the need for the recurring 500
inspection by alternate method of compliance (AMOC). Now you won't
have to remove the rudder every 500 hours, remove the hinges,
perform a dye inspection test, re-attach the hinges and re-safety wire the 2
fillister head screws (which are nestled down in-between the hinge
tabs and very difficult to access) then reinstall the rudder. Best of all your spar will never crack. Having a yaw dampener makes these essential since it applies constant corrections to the rudder during flight and side loads to the spar not felt by planes without it. |

Read the full backstory on the discovery of rudder spar cracks,
the FAA investigation and all the ADs that were issued and revised. Learn who Dick Wilson was, how he got involved
in the design of the original Space Machine Products brackets and later how he redesigned and improved the brackets
then partnered with General Forming Corp and Charles Vegher on their manufacture and distribution. |
