When considering alterations to a parachute, which statement is accurate?

The accurate statement regarding alterations to a parachute is that dyeing of a canopy is indeed considered an alteration. This is because altering the appearance of the canopy through dyeing can affect the material properties or performance characteristics of the parachute. Changes to the fabric color may impact visibility, heat absorption, or the integrity of the material, depending on the dye process used.

Replacement of a suspension line, however, is typically part of maintenance rather than an alteration. It is a common procedure aimed at ensuring the safety and functionality of the parachute system. Maintenance tasks like this are crucial for the parachute's operational capability and do not change the fundamental design or operational specifications of the parachute. Therefore, dyeing the canopy stands out as an alteration because it is a change to the parachute's original configuration and can have various implications beyond aesthetics.
