Write a research paper about retractable gear aircraft systems focusing on a review of at least two gear up landing accidents/incidents, one each of a pilot failing to extend the gear and a mechanical issue that precluded gear extension.

Research Paper
Each student will write a research paper about retractable gear aircraft systems focusing on a review of at least two gear up landing accidents/incidents, one each of a pilot failing to extend the gear and a mechanical issue that precluded gear extension. The paper should address the various lessons learned from previous such incidents, and address what measures (procedural, technological, etc.) should be adopted to prevent similar incidents from occurring in the future.

The style required for formatting the paper is American Psychological Association (APA), 7th edition, guidelines. The paper will be graded on accuracy and completeness of information, cohesiveness, spelling and grammar, and number and quality of references.
