Although the title of this replacement sound set is Piper Arrow 28 HD-Audio Package, the developer, Skysong Soundworks, states that is is appropriate to use with any PA-28 Cherokee series aircraft, not just the more complex than most Arrow.

Sampled at 44.100 kHz 16 bit and mixed to perform well in both FS9 and X, the package contains numerous additional and improved sounds, a full list of which can be found on the product page, after watching the promotional video above.
