Airbus A220の翼はイギリスで、787の胴体は日本とイタリアで成形され、737の機首はカンザスで打ち出される——そしてすべてのパーツが、最後に組立ラインで飛んで合流します。この「機体そのものを作る」会社たちがAerostructures——胴体・翼・尾翼・ナセル・締結具・鋳鍛造部品をつくり、それをAirframe OEMが受け取って組み立てる。一見「ただの金属と炭素の加工」に見える仕事が、なぜ世界に新しい飛行機がどれだけ速く行き渡るかを決める分岐点であり、サプライチェーンで最も利益の薄いビジネスであり、たった1社のサプライヤーの品質問題がBoeing全社を揺るがす脆い急所でもあるのか——このレッスンはそこを見ていきます。
ソフトウェア問題でボーイング Max 10 の認証が停止 FAAは新たに発見されたソフトウェア問題を理由に737 Max 10の認証を一時停止し、納入が遅れ、ボーイングの生産計画に不確実性が加わった。ボーイング株は最大6.8%下落した。生産の鈍化や不確実性は、航空機構造と部品サプライヤーへの短期的な受注減少を意味する。

バンク・オブ・アメリカの航空宇宙担当アナリスト、ロナルド・エプスタイン氏は、ボーイングのケリー・オートバーグCEOが9月16日にモルガン・スタンレーのラグナ会議で行った発言を受けて株価が同日中に約7%下落した後も、ボーイングに対する買い評価と270ドルの目標株価を再確認した。ボーイングは9月18日金曜日に198.20ドルで取引を終え、過去5営業日で4.83%下落、年初来では12.98%下落しており、エプスタイン氏の目標株価はこの終値から約36%の上昇を示唆している。オートバーグ氏は、社内での主翼生産のため、737の生産ラインが目標とする月産47機のペースにまだ安定していないと述べたが、737 MAX 10はまもなく認証されるはずだとし、777Xの認証試験が2027年まで延長されることを確認した。エプスタイン氏は市場の反応をやや劇的すぎると評し、短期的な真のリスクは、約1万7000人のエンジニアを代表し、契約が10月6日に期限切れとなる航空宇宙専門技術者協会によるストライキの可能性だと述べた。同組合員は9月上旬に達した4年間の暫定合意についてまだ投票する必要がある。同氏は、ボーイングの2026年のフリーキャッシュフロー予測24億ドルについて問題ないとし、737 MAX 10が737の受注残の約30%を占めていること、ボーイングの受注残高が今年初めに6950億ドルを超えていたことを指摘した。

ボーイングのケリー・オートバーグCEOは、中国からの大型航空機発注への期待を抑え、今年初めに約200機の発注を受けた事実はないと明らかにした。その上で、中国当局者はむしろ購入を進める計画を示しており、発注は段階的に現れ、個別の航空会社から発表されるとの見方を示した。モルガン・スタンレー主催の第14回ラグナ会議で講演したオートバーグ氏は、ボーイングが737の生産率を月47機に到達させたものの、その水準で安定するには至っておらず、エンジンを含むサプライチェーン全体は良好な状態にある一方、レントンでの主翼生産が依然として主要な制約となっていると述べた。ボーイングは737 MAX 10の認証がまもなく得られると見込んでおり、飛行試験は完了し、残るのは書類手続きと規制当局の審査のみで、MAX 10はボーイングの737受注残の約30%を占める。777Xは新たな障害に直面しており、ボーイングはETOPS試験を開始する前にGEエアロスペースのエンジンミッドシール認証計画の完了を待っている。一部の試験は来年にずれ込む可能性があるが、同社は2027年の引き渡し目標を維持している。エンジンの引き渡しも、ボーイングが787の生産を月8機から月10機に引き上げる取り組みを鈍らせており、必要なエンジン引き渡し実績は年末近くになると見込まれている。また、SPEEAのストライキが実施されれば、777X認証プログラムが事実上停止し、現行契約が10月6日に期限を迎える前に737の生産が混乱する可能性がある。ジェイ・マラベCFOは、ボーイングの2026年のフリーキャッシュフロー予測を10億ドルから30億ドルと再確認し、約20億ドルを枠組みとしているが、年末にかけての737と787の生産立ち上げが予想を下回るため、中間値を上回る結果は以前の予想よりも可能性が低いと述べた。
