Yes. The C-14A directional gyro can be used in place of the 332E-4 dir. gyro and 328A-3G slaving amp. However, the amplifier in the C-14A gyro is not enough to drive the compass card in the 331A-3G HSI. Therefore, the 341C-1 servo amplifier must be used in conjunction with the C-14A to function properly the Collins PN-101.

Per a Honeywell Technical newsletter , all gyros have a shelf life of 6 months. During long periods of inactivity, the lubricating oils have a tendency to creep from the spin and gimbal bearings and puddle in the bearing raceways. The performance of gyros is greatly affected by extended periods of shelf time; therefore the gyro should be inspected in order to ensure proper operation.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.
