TL-ULTRALIGHT may authorize another TL-ULTRALIGHT approved entity to perform
the evaluation of an alteration, modification or major repair who shall provide a written
affidavit that the aircraft being altered will still meet the requirements of the applicable
ASTM design and performance specification after the alteration.
TL-ULTRALIGHT or another TL-ULTRALIGHT approved entity that performs the
evaluation shall provide written instructions and diagrams on how, who, and the level of
certification needed to perform the alteration, modification or major repair.
The instructions must be approved by TL-ULTRALIGHT and must include ground and
flight testing that complies with the original ASTM production acceptance testing
standard, as appropriate, to verify the alteration, modification or major repair was
performed correctly and the aircraft is in a condition for safe operation.
TL-ULTRALIGHT or another TL-ULTRALIGHT approved entity that performs the
evaluation shall provide information to the owner of the aircraft for the documentation of
the alteration, modification or major repair in the aircraft’s records.
1.1.10 Task-Specific Training
TL-ULTRALIGHT may require type-specific training in order to accomplish a task in
either the maintenance manual or in an authorization for a major repair, maintenance, or
alteration. The FAA does not give approval to these task-specific training programs for
SLSA. TL-ULTRALIGHT may specify any task-specific training it determines is
appropriate to accomplish a task.
Examples of task-specific training include:
1. Engine manufacturer heavy maintenance or overhaul school, or both,
2. Instrument installation or repair course
3. Parachute manufacturer repair course
4. Aircraft manufacturer course.
1.1.11 Safety Directives
An SLSA aircraft may have a Safety Directive issued against an aircraft or component
part by the manufacturer. TL-ULTRALIGHT will issue any directive as outlined in the
applicable ASTM continued airworthiness specification.

1 - 8
SLSA and components installed on SLSA’s do not have Airworthiness Directives issued
against them. If an AD is issued against a type-certificated product that may be
incorporated into special light sport aircraft, T TL-ULTRALIGHT will issue a safety
directive in accordance with Document F 2295 41 to provide instruction on how to
address the safety defect outlined in the AD on the specific SLSA.
TL-ULTRALIGHT will provide applicable instructions to comply with any safety directive,
which will include:
1. A list of the tools needed to accomplish the task,
2. A list of the parts needed to perform the task,
3. Type of maintenance, line, heavy, overhaul,
4. Certification level needed to accomplish the task, RI, RM, A&P.
