Continued Operational Safety Monitoring
Manufacturer Responsibilities:
Sling Aircraft has a procedure in place to monitor the safety of the fleet
and to alert pilots of any potential safety issues. The owner of a Light-
Sport Aircraft is responsible for making sure they receive pertinent
safety information and complying with bulletins. The owner of a Light-
Sport Aircraft is also responsible for alerting the manufacturer of any
potential flight safety issues they may encounter.
Owner/Operator Responsibilities:
•Each owner/operator of an LSA shall read and comply with the
maintenance and continued airworthiness information, along
with all instructions provided by the manufacturer.
•Each owner/operator of an LSA shall be responsible for providing
the manufacturer with current contact information, where the
manufacturer may send the owner/operator supplemental
notification bulletins/letters.
•The owner/operator of an LSA shall be responsible for notifying
the manufacturer of any flight safety issues or significant service
difficulty, upon discovery.
•The owner/operator of an LSA shall be responsible for complying
with all manufacturer issued notices of corrective action and
with all applicable aviation authority regulations, with regards to
maintaining the airworthiness of the LSA.
•The owner of an LSA shall ensure that any needed corrective
action be completed as specified in a bulletin/letter/notice, or by
the next scheduled annual inspection.
•Should an owner/operator not comply with any mandatory
service requirements, the LSA shall be considered not in
compliance with applicable ASTM standards and may be subject
to regulatory action by the presiding aviation authority in the
respective region.

Revision: 3.0 Date: 2021/04/23
1.1 Introduction to Airplane
The Sling LSA is a two seat (side-by-side), single engine, tricycle
undercarriage, aluminium aircraft with a conventional low wing design
and is compliant with the requirements of the FAA Light Sport Aircraft
(LSA) category according to ASTM Standards F2245, F2279 and F2295.
The aircrafts design is based on ASTM 2245 certification standards and
has a maximum all up weight of 600kg (1,320lb). The design has been
tested against and complies with this standard.
With only minor modifications to the aircraft and the application of a
revised Pilot Operating Handbook, the aircraft may be made to comply
with the requirements of the EASA (European Aviation Safety Agency)
CS-VLA (Certification Standard Very Light Aircraft) standard, having a
maximum all up weight of 700 kg (1543 lb).
The Sling LSA is primarily intended for recreational and cross-country
flying. It is not intended for aerobatic operation. It is considered to be
suitable for use as a trainer. This Pilot Operating Handbook has been
prepared to provide pilots with information for the safe and effective
operation of the Sling LSA.
