Peruvian Airlines Flight 112

Peruvian Airlines Flight 112 is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Peruvian Airlines Flight 112 rather than just read about it. In short: Peruvian Airlines Flight 112 was a domestic scheduled passenger flight operated by a Boeing 737-300 from Lima to Jauja in Peru. On 28 March 2017, the aircraft operating the flight suffered undercarriage collapse after landing, caught fire, and was burnt out.

Reference excerpt

Peruvian Airlines Flight 112 was a domestic scheduled passenger flight operated by a Boeing 737-300 from Lima to Jauja in Peru. On 28 March 2017, the aircraft operating the flight suffered undercarriage collapse after landing, caught fire, and was burnt out. While no fatalities occurred in this accident, 39 of the 150 people on board were injured.

Accident

The aircraft landed at Jauja at 16:40 local time (21:40 UTC). Passengers reported "two strong impacts" on landing. All three landing gear legs collapsed and the aircraft slid along the runway and departed the runway to the right, and the starboard wing hit the airport's perimeter fence. A fire broke out and destroyed the aircraft. All 141 passengers and nine crew on board escaped, of whom 39 people were injured and taken to hospital. Two people sustained broken bones, and three people sustained concussions. The accident was captured by several passengers on board.

Aircraft The accident aircraft was a Boeing 737-3M8, msn 25071, registration OB-2036-P.

Investigations The Commission for the Investigation of Aviation Accidents, and the Criminal Prosecutor's Office in Jauja both opened investigations into the accident. The Commission for the Investigation of Aviation Accidents (CIAA) released its final report in November 2020 and determined that the cause of the accident was a mechanical failure of mechanical components of the shimmy damper systems on both main landing gear struts which, due to being outside of tolerance, were not able to correctly dampen the vibrations and lateral oscillations of the wheels causing "shimmy" events. The sequence of shimmy events in both main gear struts led to the fracture and collapse of both main gear struts. The Commission for the Investigation of Aviation Accidents also found other contributing factors that were the following:

An incorrect and maybe missing data about the measurements of mechanical components of the shimmy damper kinematic system that are probably not present inside the Aircraft Maintenance Manuals (AMM) that are handed over to Peruvian Airlines, the presence of this data's would have permitted to take timely detection and replacements of components that are overcome their tolerance limits; The Boeing service letter named Main Landing Gear (MLG) Lower Torsion Link Fractures does not required any mandatory action to prevent problems but only recommends maintenance actions to prevent fractures in the mechanical components of the shimmy damper system; The Boeing service letter named Main Landing Gear Lower Torsion Link Fractures is too complicated to interpret and possibly confusing about which one Aircraft Maintenance Manuals actions are to take in consideration and in which ambit.

Worked examples

Example 1 — a first encounter with Peruvian Airlines Flight 112

Start with the simplest possible case. Write down what Peruvian Airlines Flight 112 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Peruvian Airlines Flight 112 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Peruvian Airlines Flight 112 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Peruvian Airlines Flight 112

In research: Peruvian Airlines Flight 112 appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Peruvian Airlines Flight 112 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Peruvian Airlines Flight 112 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010s fires in South America, 2017 fires, 2017 in Peru, so understanding it makes those chapters shorter.
In everyday life: Look for Peruvian Airlines Flight 112 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
