Maintaining and repairing a hot air balloon

As with any aircraft a hot air balloon requires regular maintenance and repair in order to keep it airworthy. Because a balloon is made of fabric it may occasionally require repairing due to snags and rips.

While most of the maintenance such as cleaning and drying can be performed by the pilot or balloon crew, tasks like sewing and repairing the envelope must be performed by a qualified technician and be recorded in the balloons log book.

To guarantee a long and safe operation, the envelope ought to be kept clean and dry. This prevents the build up of mould and mildew, which can weaken the fabric.

The burners must also be kept clean and tidy to make sure of safe operation. Damaged or leaky fuel hoses and valves must be repaired or replaced.

If a rip or snag is discovered in the envelope fabric, it can either be patched up or the whole panel replaced. Patches are usually glued, taped or stitched on, whereas replacing a whole panel requires the new piece to be sewn in using the appropriate technique, thread and stitch pattern to ensure a strong seam.
