Preventive Maintenance and Records (# 83)
Preventive Maintenance and Records
This article highlights some of the Federal Aviation Regulations related to aircraft maintenance. While much of the required maintenance must be performed by, or under the supervision of a certified repair station, the regulations also permit the pilot to perform some preventive maintenance. These regulations, along with the balloon manufacturer´s Instructions for Continued Airworthiness, or maintenance manual, set out the requirements for the aircraft owner/operator to keep the aircraft physically and legally airworthy.
The FAR´s, written in bureaucratic language; eventually tell you what maintenance operations you are authorized to perform, and what records you are required to keep. Referrals to some applicable FAR´s are at the end of this article. Please refer to your copy of the current FAR/AIM for the complete text.
Preventive Maintenance (as defined in FAR 1.1) means simple or minor preservation operations and the replacement of small standard parts not involving complex assembly operations.
FAR 91.403 require the owner or operator of the aircraft to maintain it in airworthy condition and comply with all applicable airworthiness directives. It also refers to Part 43 which specifies who may perform different maintenance operations and endorsements. After working through the regulations, you will see that the holder of a pilot certificate is authorized to perform preventive maintenance operations, and make an entry in the maintenance records approving the aircraft, appliance, or component part for return to service. Note that the aircraft must be owned (at least in part) by the pilot.
FAR Part 43 Appendix A lists several preventive maintenance operations that the pilot/owner may perform, but it also defers to the aircraft manufacturer´s maintenance manual for specific procedures.
Examples of preventive maintenance items as defined in some manufacturers´ maintenance manuals are as follows:
(1) Removing dust, soot and debris from basket and burner when it does not require disassembly of any basket primary structure or burner assembly components.
(2) Removing dirt and debris from hook and pile fastener tapes on the deflation panel.
(3) Moistening or applying protective materials to basket wicker, or refinishing or applying protective materials to decorative furnishings of the basket such as leather upholstery when that does not require disassembly of any primary structure or interfere with the integrity of the fuel system.
(4) Replacing prefabricated fuel hoses not requiring disassembly of any threaded pipe fittings.
(5) Replenishing methanol in propane tanks.
(6) Replacing instrument batteries.
(7) Interchanging balloon baskets, burners, and cables that are specifically designed for quick removal and installation, and when such removal/installation can be accomplished by the pilot; provided that baskets are not interchanged except as provided in the Flight Manual for that balloon.
(8) Cleaning and inspection of suspension cables.
(9) Limited rattan repair.
(10) Temporary repair of fabric damage not exceeding acceptable damage limits, using adhesive backed patches.
(11) Repair of skirt fabric or envelope fabric below the first horizontal load tape.
(12) Replacement of Velcro tabs on the parachute top or envelope.
(13) Washing the envelope fabric using approved procedures.
(14) Replacing Kevlar cables or carabiners.
Most of the preventive maintenance items are different from repairs that must be performed by a repair station because they normally:
1. Do not require special tools or knowledge.
2. Do not modify the structure of the aircraft.
3. Are similar to operations performed in preparing the aircraft for flight.
Refer to the maintenance manual for your balloon to determine exactly what preventive maintenance you may perform, and how to perform it. If you do not find the answer there, contact your local repair station or the balloon manufacturer for guidance. If an operation is not considered preventive maintenance, you may be able to make arrangements for a repair station to consult with you and observe your work. If you complete the work under the direct supervision of, and to the satisfaction of the repair station, they can inspect it and authorize the aircraft to be returned to service.
After you perform preventive maintenance, make the appropriate entry in the aircraft logbook or maintenance records.
Examples of suitable endorsements are:
Gore 5 panel 7 orange, 3" adhesive patch near top center, per manufacturer´s instructions. TT=240.5 hr. Joe Pilot, Private Pilot Certificate # 123-45-6789 6-1-98
Removed tanks, cleaned basket. Varnished floor. Reassembled system. TT=405.3 hr. Jane Pilot, Commercial Pilot Certificate # 789-01-2345 4-16-98
The maintenance records for your balloon may be kept in your aircraft logbook, but they may be kept in a separate maintenance logbook. Other maintenance records include repair station work orders and 337 forms. Often the details of the repair will be spelled out in the work order. The logbook will contain either an annual/100 hour inspection endorsement, or a return to service endorsement, possibly with a listing of major repairs. It will also contain a reference to a work order number.
Under the FAR´s, a repair station is required to keep work orders for two years. They may be destroyed after 2 years. As a practical matter, I would recommend that you keep a ring binder for photocopies of your aircraft logbook or maintenance logbook, and all of the work orders you have for the balloon. The work orders are especially useful for tracking life limited parts such as fuel hoses, fuel cylinder pressure relief valves, and some suspension cables.
If you take your system to a repair station that has never seen it before, and you do not have the records available, some time consuming and expensive tests may be required, or some parts may need to be replaced that have already been replaced. If the repair station does not have the maintenance records for the system, you can not prove the work was previously performed. When they have any doubt about the required work having been done, they will quite properly do it again. If you can produce copies of the records, you can prevent unnecessary work and expense.
Please refer to the FAR/AIM parts listed below for more details. All of the parts listed below, except for Part 39, are included in the paper FAR/AIM book that most pilots already own. These documents are also available through the Internet at the following URL:

If you have Internet access, and would like to know the reasons for your balloon system´s design, look at FAR Part 31 -- Airworthiness Standards: Manned Free Balloons. This is the standard that many of the world´s balloon manufacturers use to design balloon systems for sale in the US. Some foreign agencies have added other requirements to this standard, such as the requirements for higher basket sides.
