CONTINUED AIRWORTHINESS FOR ZENAIR AIRCRAFT DESIGNS
This important information is intended for builders, owners and operators of Chris Heintz (CH) aircraft designs.
Please remember that the primary sources of reference for the assembly, maintenance and repair of these amateur-built (Experimental) aircraft are the TECHNICAL DRAWINGS and the Zenair Construction Standards ("CS") manual. To ensure the structural integrity of your aircraft, make certain that every aspect of the airframe is made, assembled and functioning in accordance with the drawings and CS manual. If you purchased the aircraft complete (used) and never received the drawings, contact Zenith Aircraft Co. and obtain a replacement copy (nominal fee involved).
If your Zenair aircraft was factory-built (certified) and never sold with a set of drawings, the Zenair Construction Standards still apply and owners are in addition obligated to comply with the factory-supplied POH and Maintenance manuals. Mechanics working on such aircraft (for maintenance and repairs), can use the available parts catalogs for appropriate part numbers when ordering replacement parts from Zenair (see below for links).

Airworthiness Directives, Service Bulletins, Service Letters, etc.
Every now and then, Zenair is made aware through customer feedback and/or through field experience, that a specific element in a Zenair design should be double-checked, modified or replaced to best ensure the continued airworthiness of the aircraft. Depending on the nature of the finding (and the category of the aircraft), Zenair may issue a Service Letter, a Service Bulletin or an Airworthiness Directive (AD). Copies of these documents are posted on-line and are accessible 24/7 to Zenair aircraft builders, owners, operators and mechanics - at no cost. IMPORTANT: Remember that responsibility for compliance with applicable ADs, Bulletins and Letters always rests with the aircraft owner.

ZENAIR NEWS:
Zenair News is no longer published (last issue: Summer 2012). It is strongly recommended that kit builders and owners purchase the Newsletter DVD (all issues published between the 1970’s and Summer 2012!). There is a lot of valuable technical, maintenance and continued airworthiness information on this DVD that owners of "CH" type aircraft will find useful.
