L&L Aerospace Consulting-Aeronautical Services

L &L Aerospace Consulting and Aeronautical Services is a trusted partner for aircraft owners, operators and buyers seeking clarity and confidence in aircraft evaluations and operations. Provides hands-on aircraft inspections supervision, maintenance, tech-audits, pre-buy evaluations and operational consulting, focusing on safety, efficiency and cost transparency.

Setting it apart is the team with over fifty years of hands-on experience in aviation. At the core of this legacy are brothers. Luiz Octavio Mendes Machado, ANAC/FAA A&P/Sipaer Accident Prevention/Judiciary Expert senior consultant, and Luiz Sergio Mendes Machado, ANAC/FAA A&P/Judiciary Expert, senior consultant, Aircraft Maintenance Technologist and Aeronautical Engineer. They began their careers in a family-run aviation shop and have since also become recognized authorities in the technical, operational, and regulatory aspects of executive 91 and 135 operations.

“We have extensive experience across a wide range of aircraft, and for many years, clients have sought us out specifically for our technical expertise,” says Luiz Octavio.

They have worked across all Falcon models, Embraer and Gulfstream systems, offering specialized knowledge in structures, avionics and maintenance programs. Their deep familiarity with manufacturers and regulatory requirements enables them to resolve complex issues, prevent unnecessary costs and support clients with everything from shop oversight to setting up certified operations. These services have helped quietly build L&L’s reputation within Brazil’s executive aviation community. The strong industry presence directly results from years of trusted relationships, technical credibility and a proven track record of delivering results.

Numerous real-world scenarios testify to how its deep technical expertise and principled approach led to major cost savings and operational advantages.

In one notable case during a pre-buy inspection, the shop initially planned to remove the aircraft wing to carry out a repair, an expensive and invasive solution. L&L worked directly with the aircraft manufacturer’s engineering team to identify an alternative approach that avoided wing removal entirely. This solution preserved structural integrity and saved the client over $1 million.

Building on their history of delivering cost-saving solutions, L&L’s meticulous attention to detail has consistently uncovered overpricing service invoices. Luiz Octavio has over 26 years of experience just managing Dassault Falcon aircraft for a private company, Luiz Sergio also has over 30 years managing Gulfstream and Dassault fleet during which they helped several companies save millions in maintenance and return costs.

L&L also provides expert advisory services in legal and insurance-related matters. Recognized as technical experts by the judiciary, the company is often called upon by insurance firms to investigate incidents and offer professional assessments. Luiz Sergio, with extensive expertise in avionics and various aircraft models, plays a key role in these evaluations.

When it comes to aircraft purchase and sale contracts, L&L’s combined engineering and legal expertise uncovers technical issues that might otherwise go unnoticed. Careful scrutiny helps clients avoid costly errors and make well-informed transaction decisions.

L&L brings more than just technical knowledge to its services. Strong ethics firmly guide it, consistently refusing to cut corners or approve repairs unless they are fully justified and safe.

This approach focuses on saving money only when it can be done without compromising safety, prioritizing long-term value and reliability over short-term cost reductions. In aviation, safety always comes first and therefore this criterion must prevail over all others.

With an unflinching commitment to quality and safety, L&L Aerospace Consulting and Aeronautical Services continues to be the go-to expert for clients seeking reliable guidance and technical excellence across every stage of aircraft ownership and operation.
