Read the first 7 Installation Techniques flashcards as text

  1. What type of safety wire is required when safety-wiring a set of three closely-spaced bolts in a triangular pattern?

    Answer: A double-strand twisted wire linking all three in a daisy-chain pattern

    Three bolts in close proximity are safety-wired with a single continuous double-strand twisted wire connecting all three in sequence.

  2. A technician is installing a new fuel selector valve. After installation, what is the FIRST check to perform?

    Answer: Confirm the valve operates through all positions without binding

    Valve freedom of movement must be verified before any pressure is applied to ensure no binding or interference that could prevent proper fuel selection.

  3. When torquing a nut on an AN bolt, what should the technician do if the torque wrench reaches the specified value before the cotter pin hole aligns?

    Answer: Continue tightening beyond the specified torque until the holes align

    Torque specifications are a minimum; the nut may be tightened further within the maximum limit to achieve cotter pin hole alignment, but never backed off.

  4. Which statement is correct regarding the installation of Dzus fasteners on an access panel?

    Answer: Dzus springs must be installed with the open end facing forward

    Dzus fastener springs must be installed with the open end facing forward (into the airflow) to prevent the spring from scooping air and potentially detaching.

  5. What type of fitting is used to connect flexible hydraulic hose to a rigid tube when both are part of the same hydraulic system?

    Answer: A compatible AN or MS flared or flareless fitting

    Compatible AN or MS fittings are used to connect flexible hose to rigid tubing, ensuring pressure integrity and system compatibility.

  6. When installing a battery in an aircraft, why must the battery be secured with the specified hold-down hardware?

    Answer: To prevent movement that could short battery terminals or damage structure

    Battery hold-down hardware prevents movement under dynamic loads, which could cause terminal shorts, structural damage, or loss of electrical power.

  7. What is the effect of installing a thicker gasket than specified between an engine accessory and its mounting pad?

    Answer: Drive shaft or coupling misalignment may result

    An oversized gasket changes the spacing between mating flanges, causing misalignment of drive shafts or couplings that can lead to component failure.
