New simplified maintenance rules for SZD-51-1 Junior, life-limit doubled

As the Type Certificate Holder for SZD‑51-1 Junior we would like to inform the users about the possiblity to transition to a simplified maintenance of all SZD‑51-1 Juniors. Also, we inform about the possibility of extending life‑limit for all the Juniors which have reached 6.000 FH. The new life‑limit is 12.000 FH.


The simplified maintenance system involves replacing the current duties of scheduled inspections like  50-, 100-, 200 Flight Hours as well as “before and after the season” with an annual inspection and/or after every 300 FH only. This solution will significantly reduce operating costs and keep the glider in continuing airworthiness throughout the whole season.

Another advantage of the simplified system is the extension of the intervals between the main scheduled checks. In place of the existing checks after each 1.000 FH, the checks performed every 1.500 FH were introduced.

However, we would like to remind to the pilots, as the simplified maintenance system dos not allow to omit precisely made daily pre- and post‑flight inspections, as this is the main duty of the pilot‑owner. All findings, also during the flight (like overspeeding, overloading etc.) must be obligatory reported to the maintenance, and than - before the next take‑off  - removed and approved by the approved staff.

Please note, however, that the simplified system does not relieve the pilots/users of careful check of the glider before and after the flight (flights) and obligatory reporting to the approved maintenance staff any special cases in flight (exceeding usage conditions like overspeeding, overloading etc.) and damages caused on the ground.

The rules of unscheduled inspections (ie. after a hard landing) remain unchanged.

Details are described in the service bulletin BE‑013/51‑1/2016 available at the Allstar PZL Glider (contact through at a price of 360 EUR net. With the service bulletin, you will receive a new issue of Flight Manual and Maintenance Manual.

Gliders, which have not reached 6.000 FH may still be operated and maintained in accordance with the existing rules (see Index of Service Publications).
