This sixteen item checklist are the instructions for Continued Airworthiness (ICA), to comply with FAA Handbook Bulletin for Airworthiness (HBAW 98-18 Dated October 7,1998), are applicable to the aircraft listed above when the following equipment is installed.

System: Electrically driven vacuum pump as a standby auxiliary pump to existing pump STC No._____

Introduction: This section briefly describes the aircraft, engine, propeller, or component that has been altered.  Include any other information on the content, scope, purpose, arrangement, applicability, definitions, abbreviations, precautions, units of measurements, referenced publications, and distribution of the ICA as applicable.

Comments: Installation of a standby vacuum system.  The Guardian I standby vacuum system is connected to the existing aircraft vacuum system to provide vacuum in case of primary pump failure. The system is electric and is a continuous operational system.
Description:  Of the major alteration, its functions, include an explanation of its interface with other systems, if any.

Comments: To provide a vacuum source for the vacuum operated instrument in the event of a primary pump failure.
Control: Operation information: Or special procedures, if any.

Comments: The Guardian I should be operated in accordance to the operational procedures provided by Aero Safe Corporation.  The Guardian I should be on during ICM flight conditions.
Servicing Information:  Such as types of fluids used, servicing points, and location of access panels, as appropriate.

Comments:  The motor drive/ pump/ base plate assembly is located on the firewall.  Annual/ 100 hour inspection instructions are provided by Aero Safe Corporation.

Maintenance Instructions:  Such as recommended inspection/maintenance period in which each of the major alteration components are inspected, cleaned, lubricated, adjusted, tested, including applicable wear tolerance and work recommended at each scheduled maintenance period.  This section can refer to the manufacturers’ instruction for the equipment installed where appropriate (e.g. functional check, repairs and inspections.) It should also include any special notes, cautions, or warnings, as applicable.

Comments:  Aero Safe Corporation recommends that the system be activated and run continuously for a minimum of 20 minutes every quarters (3-4 months) Ref. Aero Safe Corporation Annual 100 hour inspection provided.
Troubleshooting Information:  Information describing probable malfunctions, how to recognize those malfunctions, and the remedial action to be taken.

Comments: System fails to operate (1) check fuse (2) rotate drive shaft connecting the motor drive to vacuum pump ( turns freely).  If system continues to malfunction call Aero Safe Corporation for evaluation.
Removal and replacement information:  This section describes the order and method of removing and replacing products, parts and any necessary precautions.  This section should also describe or refer to manufacturer’s instructions to make required tests, trim checks, alignment, calibrations, center of gravity changes, lifting or shoring, ect… if any.

Comments:  Removal and replacement: refer to Installation Manual and contact Aero Safe Corporation.
Diagrams:  Of access plates and information, if needed, to gain access for inspection.

Comments:  The Guardian ! is installed on the aircraft firewall.  Remove upper and lower cowling for access.
Special inspection requirements:  Such as X-ray, ultrasonic testing. magnetic particle inspection, if required.

Comments:  No special inspection required other than the Annual/100 Hour inspection provided.
Application of protective treatments:  To the affected area after inspection and/or maintenance, if any.

Comments: none required.
Data:  Relative to structural fastener such as type, torque, and installation requirement, if any.

Comments: none required: See installation manual.
List of special tools:  Special tools that are required if any.

Comments: No special tools required.
For commuter category aircraft:  The following additional information must be furnished, as applicable:
A. Electrical loads
B. Methods of balancing flight controls
C. Identification of primary and secondary structures.
D. Special repair methods applicable to the airplane.

Comments: N/A
Recommended overhaul periods:  Are required to be noted on the ICA when an overhaul period has been set by the manufacturer of a component, or equipment.  If there is no overhaul period, the ICA should state for item 14: “No additional overhaul time limitations.”

Comments:  No additional overhaul time limitations.
Airworthiness Limitation Section:  Include any “approved” airworthiness limitations identified by the manufacturer or FAA Type Certificate Holding Office (e.g., An STC incorporated in a larger field approved major alteration may have an airworthiness limitation.)  The FAA inspector should not establish, alter, or cancel airworthiness limitations without coordinating with the appropriate FAA Type Certificate Holding Office.  If there are no changes to the airworthiness limitations, the ICA should state for item 15: “No additional airworthiness limitations: or “Not Applicable.”

Comments:  No additional airworthiness limitations.
Revision:  This section should include information on how to revise the ICA.  For example, a letter will be submitted to the local FSDO with a copy of the revised FAA Form 337 and revised ICA.  The FAA inspector accepts the changes by signing Block 3 and including the following statement:  “ The attached revised/new Instructions for Continued Airworthiness (Date______) for the abore aircraft or component major alteration has been accepted by the FAA, superseding the Instructions for Continued Airworthiness (Date_____).”  Once the revision has b een accepted, a maintenance record entry will be made, identifying the revision, its location, date of the Form 337.

Comments:  Any revisions of the ICA will be made/approved by Aero Safe Corporation.

Implementation and Record Keeping:  For major alteration performed in accordance with FAA Field Approval policy, the owner/operator under part 91 is responsible for ensuring that the ICA is made part of the applicable section 91.409 inspection program for their aircraft.  This is accomplished when a maintenance entry is made in the aircraft’s maintenance record in accordance with section 43.9.  This entry records the major alteration and identifies the original ICA location (e.g. Block8 of FAA for 337, dated 5/28/98) along with a statement that the ICA is  now part of the aircraft’s inspection/maintenance requirements.

For major alterations performed in accordance with a field approved on air carrier aircraft, the air carrier operator is responsible for ensuring that the ICA is made part of the applicable inspection/maintenance requirements.  If a procedure is not currently included in the operator’s manual to incorporate ICA, this process will need to be appropriately addressed (i.e. the operator submits a revision to its maintenance program to the applicable certificate-holding district office (CHDO).

For aircraft inspected under an Approved Aircraft Inspection Program (AAIP), the operator will submit a chance to the CHDO in accordance with section 135.419b.

For air carrier aircraft inspected using an annual/100 hour inspection program, a reference to the new ICA will be made in the aircraft’s maintenance record in accordance with section 43.9.  This entry records the major alteration and identifies the original ICA location (e.g., ICA are located/attached to Block 8 of FAA Ford 337, date 5/28/98).  In addition, the operator will request a revision to the operator’s Operation Specifications, additional maintenance requirements, which incorporates the ICA into the inspection program.
