Requires replacement of the forward and aft wire pull fittings on certain of the affected airplanes. AD is prompted by an investigation finding the fittings are prone to stress corrosion cracking at low cycles/hours. Failure of these wire pull fittings will reduce the strength of the float undercarriage below the required structural capability and could result in a failure of the undercarriage causing the air to tip over and be submerged.
