Packing guide

How to pack an instrument

Instruments are built to take vibration in the panel, not drops in a parcel hub. A few minutes of careful packing protects the gyro bearings, pressure diaphragms and cover glass.

Every instrument

  • Use a sturdy box with at least 2 inches of foam or bubble wrap on every side. Skip packing peanuts: they shift, and the instrument settles to the bottom.
  • Pack it face up, with the cover glass and knobs wrapped.
  • Sending more than one? Keep the instruments from touching.
  • Ship with tracking, and insure the package for the instrument's value.
  • Put a copy of your service request in the box.

Gyro instruments

  • Let the gyro spin down completely before you remove it. It can keep spinning for several minutes after the power is off.
  • Cap the air fittings on vacuum instruments.
  • Double-box it: pack the wrapped gyro in a small box, then cushion that box inside a larger one.
  • Mark the box fragile. Gyros should be handled like eggs.

Pressure instruments

  • Cap the pitot and static fittings, and don't blow into them.
  • Use caps or plugs on the fittings rather than tape, which can leave adhesive inside.
  • Note what failed in your request, such as a missed 24-month check or a reading off field elevation.
