✅ CHECKLISTS.

To inspect an airplane for corrosion and make sure that no area is left uninspected, mechanics should use checklists. Checklists help organize the inspection and ensure all corrosion-prone areas are reviewed systematically.

✅ A BENDING FORCE.

When the aerodynamic lift force on the wing tries to raise the wing, the airplane structure experiences a bending force. This force tends to bend the wing upward because lift acts upward while the aircraft weight and structural loads resist that movement.

✅ DAN 21.

Los requisitos para que una Aeronave Deportiva Liviana (LSA) sea elegible para obtener un Certificado de Aeronavegabilidad otorgado por la DGAC están establecidos en la DAN 21, ya que esta norma regula la certificación de productos aeronáuticos, partes y certificados de aeronavegabilidad.

El DAP 08 06 se relaciona con procedimientos de renovación, pero la base normativa de elegibilidad corresponde a la DAN 21.

✅ THE STRENGTH.

In certain aircraft structures, the principal requirement may be strength. This means the structure must be able to withstand the loads and stresses imposed during flight, landing, and ground operations without failing.

✅ IN ANY INSPECTION.

Inspection for corrosion is recommended during any aircraft inspection, not only annually. Corrosion can develop in hidden areas, so mechanics must always look for early signs such as discoloration, deposits, pitting, or surface damage.

✅ TO PREVENT DAMAGE.

Relief valves are used in pneumatic systems to prevent damage caused by excessive pressure. When pressure rises above a safe limit, the relief valve opens and releases pressure, protecting components, lines, seals, and equipment.

✅ END LOADS RATHER THAN SIDE LOADS.

In most cases, structural members are designed to carry end loads rather than side loads. End loads act along the length of the member, allowing it to resist tension or compression more efficiently, while side loads can cause bending and reduce structural strength.

✅ A TRICYCLE GEAR ARRANGEMENT.

The tricycle landing gear arrangement is the most used in modern aircraft. It has two main landing gear units and one nose gear, which improves ground stability, forward visibility, braking control, and handling during taxi, takeoff, and landing.

✅ FALLAS LATENTES.

Cuando la alta gerencia de mantenimiento no exige el cumplimiento de procedimientos, se generan condiciones inseguras dentro del sistema. Estas no siempre producen un accidente de inmediato, pero quedan “ocultas” en la organización hasta combinarse con errores operacionales o fallas activas. Por eso se denominan fallas latentes.

✅ THEY ARE USED TO SMOOTH AND ENLARGE HOLES TO EXACT SIZE.

Reamers are used to smooth and enlarge drilled holes to an exact size. They are not mainly for rough drilling, but for finishing a hole accurately so bolts, rivets, or fittings can seat properly.
