Amigos,
AOPA responded thusly to an inquiry about what they knew about the proposed 336/337 SID:
Paul,
John Collins asked me to respond to your question on the Cessna SID program. The Cessna SID program goes back a few years as you mention below and Cessna is working on developing SID programs for most of their fleet. For the majority of operators complying with Cessna SIDs is not mandatory.
The recent issue with the C-425/441 SID surrounded the fact that those aircraft fall under FAR 91.409(e) and (f) and have to be on an approved maintenance plan. Most C-442/441are maintained on the Cessna factory plan, as these plans meet the requirements for 91.409. When Cessna updated their maintenance plan to include the SID these owners asked for clarification of their regulatory responsibility under 91.409, and in some cases the SID is required.
Because the Cessna 337 does not meet the requirements of FAR 91.409(e) a Cessna SID would not be mandatory for owners/operators of these aircraft. I've include 91.409(e) and (f) below. I hope this helps.
e) Large airplanes (to which part 125 is not applicable), turbojet multiengine airplanes, turbopropeller-powered multiengine airplanes, and turbine-powered rotorcraft. No person may operate a large airplane, turbojet multiengine airplane, turbopropeller-powered multiengine airplane, or turbine-powered rotorcraft unless the replacement times for life-limited parts specified in the aircraft specifications, type data sheets, or other documents approved by the Administrator are complied with and the airplane or turbine-powered rotorcraft, including the airframe, engines, propellers, rotors, appliances, survival equipment, and emergency equipment, is inspected in accordance with an inspection program selected under the provisions of paragraph (f) of this section, except that, the owner or operator of a turbine-powered rotorcraft may elect to use the inspection provisions of §91.409(a), (b), (c), or (d) in lieu of an inspection option of §91.409(f).
(f) Selection of inspection program under paragraph (e) of this section. The registered owner or operator of each airplane or turbine-powered rotorcraft described in paragraph (e) of this section must select, identify in the aircraft maintenance records, and use one of the following programs for the inspection of the aircraft:

Whether the FAA proceeds to require compliance by AD (as occured with the 400 series twin Cessnas), and/or whether insurance companies will attempt to encourage compliance, are different questions.
Therofer, it behooves us to pay close attention to this developing saga.
