What STCs are available?
Sandel Avionics has received an FAA supplemental type certificate (STC) approval for the SN3308 installed in a Beech F33A Bonanza. This STC is the certification basis not only for Bonanzas but also for follow-on installations in other aircraft. The FAA Flight Standards Office has issued a memorandum which specifically states that the SN3308 is eligible for field approval without the need for an airframe-specific STC.
