PLT182: Inspecting The Envelope Fabric

What code PLT182 covers, why the FAA tests it, and how to study Inspecting The Envelope Fabric before your checkride.

Recall balloon - inspecting the fabric

What this means for your checkride

The preflight inspection is the systematic check by which a pilot determines the balloon is airworthy, and for balloons it is usually done as part of layout and inflation. The envelope fabric is examined for tears, damage, and patches, since the fabric carries the flight loads and its condition directly affects airworthiness. Fabrics also become increasingly porous with age and heat exposure, which raises heat loss and reduces the useful life of the envelope.

The envelope is the primary structure, so recognizing fabric damage and wear during preflight is essential to airworthiness.

The common trap

Envelope fabric does not last indefinitely. Age, heat, and porosity degrade it over time even when there is no obvious tear.

Before your checkride (14 CFR 61.39)

A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
