What this page is: a restatement of what the official Federal Register
and manufacturer records show as of the date listed below each item. It is not
a determination that any specific aircraft or engine is, or is not, in compliance.
Under 14 CFR §91.403 and §91.417, the aircraft owner/operator is responsible
for maintaining airworthiness and required records. Always verify against the official FAA
and manufacturer sources linked below before making a maintenance or airworthiness decision.

Airworthiness Directives; MORAVAN a.s. Model Z-242L Airplanes
This amendment adopts a new airworthiness directive (AD) that applies to all MORAVAN a.s. (Moravan) Model Z-242L airplanes. This AD establishes a technical service life for these airplanes by restricting Acrobatic and Utility category operations and requiring replacement of the wings after a certain operational time period. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Czech Republic. The actions specified by this AD are intended to prevent structural failure of the wing due to fatigue cracking. Such failure could result in a wing separating from the airplane with consequent loss of airplane control.

Airworthiness Directives; MORAVAN a.s. Model Z-242L Airplanes
This document supersedes Airworthiness Directive (AD) 2003-03- 13, which currently establishes a technical service life for MORAVAN a.s. (Moravan) Model Z-242L airplanes by restricting Acrobatic and Utility category operations and requiring replacement of the wings after a certain operational time. AD 2003-03-13 resulted from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Czech Republic. The restrictions required by AD 2003- 03-13 only take account for the aerobatic load spectrum and do not account for the aerobatic frequency. The restrictions also address the life limit of the wings when they should address the life limit of the entire airframe (life limit of the airplane). Although the aerobatic frequency will extend the operational times, it more importantly will ensure that all airplanes (even those that have not reached the operational limits) are not subject to fatigue cracking caused by exceeding the aerobatic frequency. This AD will maintain the restrictions of AD 2003-03-13, but will incorporate the aerobatic frequency and life limit the airplane instead of just the wings. The actions specified by this AD are intended to prevent structural failure of the wing due to fatigue cracking. Such failure could result in a wing separating from the airplane with consequent loss of airplane control.

We are superseding Airworthiness Directive (AD) 2003-11-12 for ZLIN AIRCRAFT a.s. Model Z-242L airplanes (type certificate previously held by MORAVAN a.s.). This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a need to incorporate new revisions into the Limitations section, Chapter 9, of the FAA-approved maintenance program (e.g., maintenance manual) to impose new or more restrictive life limits on critical components. We are issuing this AD to require actions to address the unsafe condition on these products.

Airworthiness Directives; MORAVAN a.s. Models Z-143L and Z-242L Airplanes
This amendment adopts a new airworthiness directive (AD) that applies to certain MORAVAN a.s. (Moravan) Models Z-143L and Z-242L airplanes. This AD requires you to modify the engine secondary vent line. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Czech Republic. The actions specified by this AD are intended to prevent the engine crankcase ventilation lines from freezing during flight in cold weather (winter) conditions, which could result in oil leaking from the engine. Such a condition could lead to engine failure.
